Abstract

A display device includes a display panel, a polarization member facing the display panel, a cover window including an inorganic material and facing the display panel with the polarization member therebetween, and a window bonding member which is between the cover window and the polarization member attaches the cover window to the polarization member. The window bonding member which attaches the cover window to the polarization member has a modulus of about of 1 MPa to about 10 MPa.

First claim

What is claimed is:

1. A display device comprising:
a display panel;
a polarization member over the display panel;
a cover window over the polarization member;
a polymer film layer under the display panel;
a polymer film bonding member between the polymer film layer and the display panel and configured to bond the polymer film layer to the display panel,
wherein the polymer film bonding member has a modulus of greater than 1 megapascal to about 10 megapascals.

2. The display device of claim 1 , further comprising a window bonding member between the cover window and the polarization member and configured to bond the cover window to the polarization member,
wherein the window bonding member has a modulus smaller than the modulus of the polymer film bonding member.

3. The display device of claim 1 , further comprising a cover window protection layer over the cover window; and
a protection layer bonding member between the cover window protection layer and the cover window and configured to bond the cover window protection layer to the cover window.

4. The display device of claim 3 , wherein the protection layer bonding member has a modulus smaller than the modulus of the polymer film bonding member.

5. The display device of claim 3 , further comprising a window bonding member between the cover window and the polarization member and configured to bond the cover window to the polarization member,
wherein the window bonding member has a modulus smaller than a modulus of the protection layer bonding member.

6. The display device of claim 5 , further comprising:
a buffer member under the polymer film layer; and
a heat dissipation member under the buffer member.

7. The display device of claim 6 , further comprising a heat dissipation bonding member between the heat dissipation member and the buffer member and configured to bond the heat dissipation member to the buffer member,
wherein the heat dissipation bonding member has a modulus smaller than the modulus of the polymer film bonding member.

8. A display device comprising:
a display panel;
a polarization member over the display panel;
a cover window over the polarization member;
a cover window protection layer over the cover window;
a protection layer bonding member between the cover window protection layer and the cover window and configured to bond the cover window protection layer to the cover window;
a window bonding member between the cover window and the polarization member and configured to bond the cover window to the polarization member; and
a polarization portion bonding member between the polarization member and the display panel and configured to bond the polarization member to the display panel,
wherein the protection layer bonding member has a modulus of greater than 1 megapascal to about 10 megapascals.

9. The display device of claim 8 , wherein the window bonding member has a modulus smaller than the modulus of the protection layer bonding member.

10. The display device of claim 9 , further comprising:
a polymer film layer under the display panel; and
a polymer film bonding member between the polymer film layer and the display panel and configured to bond the polymer film layer to the display panel,
wherein the polymer film bonding member has a modulus greater than the modulus of the window bonding member.
