Abstract

A display device includes a front panel wholly bonded on a display part of a display module via OCR (a transparent optical elastomeric resin). If a dam for preventing the OCR from being infiltrated is overflowed, the OCR is inhibited from being infiltrated and diffused into an inside of the module. The display device includes a display module including upper and lower substrates, a case receiving the upper and lower substrates, and a bezel with an opened display part, mounted in the case part, and further including a front panel wholly bonded on a display part of the display module described above via a transparent optical elastomeric resin, and a resin dam disposed on a surface of the upper substrate along an open end of a reverse side of the bezel part, wherein at least a part of the resin dam is apart from the bezel part.

First claim

What is claimed is:

1. A display device comprising a display module comprising upper and lower substrates bonded together, a case part for receiving the upper and lower substrates described above, and a bezel part which has an opened display part and which is mounted in the case part, and further comprising a front panel wholly bonded on a display part of the display module described above via a transparent optical elastomeric resin, and a resin dam disposed on a surface of the upper substrate along an open end of a reverse side of the bezel part, wherein at least a part of the resin dam is apart from the bezel part, and a resin flow-inhibiting member having a resin absorbing property which is disposed apart from the resin dam is provided in at least a part of a space part between the reverse side of the bezel part and the surface of the upper substrate.

2. A display device comprising a display module comprising upper and lower substrates bonded together, a case part for receiving the upper and lower substrates described above, and a bezel part which has an opened display part and which is mounted in the case part, and further comprising a front panel wholly bonded on a display part of the display module described above via a transparent optical elastomeric resin, and a resin dam disposed on a surface of the upper substrate along an open end of a reverse side of the bezel part, wherein at least a part of the resin dam is apart from the bezel part, and a resin flow-inhibiting member having no resin absorbing property which is disposed in contact with the resin dam is provided in at least a part of a space part between the reverse side of the bezel part and the surface of the upper substrate.

3. The display device according to claim 1 , wherein the resin flow-inhibiting member described above is adhered and fixed to any one of the reverse side of the bezel part and the surface of the upper substrate and is not adhered and fixed to the other thereof, and an aperture is present between them.

4. The display device according to claim 2 , wherein the resin flow-inhibiting member described above is adhered and fixed to any one of the reverse side of the bezel part and the surface of the upper substrate and is not adhered and fixed to the other thereof, and an aperture is present between them.

5. The display device according to claim 1 , wherein the resin flow-inhibiting members are adhered and fixed independently to both of the reverse side of the bezel part and the surface of the upper substrate respectively, and an aperture is present between the opposite resin flow-inhibiting members.

6. The display device according to claim 2 , wherein the resin flow-inhibiting members are adhered and fixed independently to both of the reverse side of the bezel part and the surface of the upper substrate respectively, and an aperture is present between the opposite resin flow-inhibiting members.

7. The display device according to claim 3 , wherein the resin flow-inhibiting member has an approximately flat, waved or irregular form on a surface thereof which is opposite to the aperture.

8. The display device according to claim 4 , wherein the resin flow-inhibiting member has an approximately flat, waved or irregular form on a surface thereof which is opposite to the aperture.

9. The display device according to claim 5 , wherein the resin flow-inhibiting member has an approximately flat, waved or irregular form on a surface thereof which is opposite to the aperture.

10. The display device according to claim 6 , wherein the resin flow-inhibiting member has an approximately flat, waved or irregular form on a surface thereof which is opposite to the aperture.

11. The display device according to claim 1 , wherein the resin flow-inhibiting member has an approximately rectangular or wedge form on a cross section thereof which is orthogonal to a display face of the display part.

12. The display device according to claim 2 , wherein the resin flow-inhibiting member has an approximately rectangular or wedge form on a cross section thereof which is orthogonal to a display face of the display part.

13. A display device comprising a display module comprising upper and lower substrates bonded together, a case part for receiving the upper and lower substrates described above, and a bezel part which has an opened display part and which is mounted in the case part, and further comprising a front panel wholly bonded on a display part of the display module described above via a transparent optical elastomeric resin, and a resin dam disposed on a surface of the upper substrate along an open end of a reverse side of the bezel part, wherein the resin dam is brought into contact with the bezel part; a resin flow-inhibiting member having a resin absorbing property which is disposed apart from the resin dam is provided in at least a part of a space part between the reverse side of the bezel part and the surface of the upper substrate; and the transparent optical elastomeric resin is present in at least a part of the space part between the reverse side of the bezel part and the surface of the upper substrate.

14. The display device according to claim 13 , wherein a resin flow-inhibiting member which is disposed in contact with the resin dam and which does not have a resin absorbing property is further provided in at least a part of the space part between the reverse side of the bezel part and the surface of the upper substrate.

15. The display device according to claim 13 , wherein the resin flow-inhibiting member described above is adhered and fixed to any one of the reverse side of the bezel part and the surface of the upper substrate and is not adhered and fixed to the other thereof, and an aperture is present between them.

16. The display device according to claim 13 , wherein the resin flow-inhibiting members are adhered and fixed independently to both of the reverse side of the bezel part and the surface of the upper substrate respectively, and an aperture is present between the opposite resin flow-inhibiting members.

17. The display device according to claim 15 , wherein the resin flow-inhibiting member has an approximately flat, waved or irregular form on a surface thereof which is opposite to the aperture.

18. The display device according to claim 16 , wherein the resin flow-inhibiting member has an approximately flat, waved or irregular form on a surface thereof which is opposite to the aperture.

19. The display device according to claim 13 , wherein the resin flow-inhibiting member has an approximately rectangular or wedge form on a cross section thereof which is orthogonal to a display face of the display part.
