Abstract

To provide a display device of high quality and high reliability by securely sealing the gap between the bezel and the display panel even when variation is generated in the gap. The display device includes: a display panel including a display face; a bezel which includes a frame part and an aperture end that is on the inner side of the frame part, and covers the fringe of the display panel on the display face side by the frame part; a frontal panel provided by sandwiching the bezel on the display face side of the display panel; and a resin member provided along the whole circumference of the aperture end of the bezel. The resin member has a first resin member formed on the display face and a second resin member formed to cover over the first resin member and a surface of the bezel opposing to the frontal panel.

First claim

What is claimed is:

1 . A display device, comprising:
a display panel which includes a display face; a bezel which includes a frame part and an aperture end on an inner side of the frame part, and covers a fringe of the display panel on the display face side with the frame part; a resin member provided along a whole circumference of the aperture end of the bezel; and a frontal panel provided on the display face side of the display panel in a state of sandwiching the bezel, wherein the resin member includes a first resin member formed on the display face, and a second resin member formed to cover over the first resin member and at least a surface of the bezel opposing to the frontal panel.

2 . The display device as claimed in claim 1 , further comprising an optical elastic resin that is filled between the display face and the frontal panel.

3 . The display device as claimed in claim 1 , wherein
the second resin member is formed to reach the display face further.

4 . The display device as claimed in claim 1 , wherein
the second resin member is formed only in a part of the whole circumference of the aperture end.

5 . The display device as claimed in claim 1 , further comprising an adhesive member which is provided on the surface of the bezel opposing to the frontal panel and on an outer circumference of the resin member, and adhesively fixes the bezel and the frontal panel.

6 . The display device as claimed in claim 5 , wherein:
the bezel and the frontal panel are in a square shape; and the adhesive member is provided only in four corners of the bezel.

7 . The display device as claimed in claim 5 , wherein:
the bezel and the frontal panel are in a square shape; and the adhesive member is provided in four sides of the bezel except for the four corners.

8 . The display device as claimed in claim 7 , wherein
the adhesive member is provided only in each center of the four sides.

9 . The display device as claimed in claim 5 , further comprising a shield substrate which is provided on the surface of the frontal panel opposing to the display face and includes a surface where a transparent conductive film is formed, wherein
at least an uppermost resin member of the resin member or the adhesive member is formed with a conductive material, and the transparent conductive film and the bezel are electrically connected via the conductive material.

10 . A method for manufacturing a display device which comprises a display panel including a display face, a bezel including a frame part and an aperture end on an inner side of the frame part, and a frontal panel, the method comprising:
a step of forming a first resin member by covering a fringe of the display panel on the display face side with the frame part of the bezel and applying a resin on the display face along a whole circumference of the aperture end of the bezel; a step of forming a second resin member by applying a resin to cover over the first resin member and a surface of the bezel opposing to the frontal panel; and a step of laminating the frontal panel to the display face side of the display panel where the first resin member and the second resin member are formed.

11 . The manufacturing method of the display device as claimed in claim 10 , further comprising, before the step of laminating the frontal panel to the display face side of the display panel, a step of applying an optical elastic resin on the display face that is surrounded by the first resin member and the second resin member.

12 . The manufacturing method of the display device as claimed in claim 10 , further comprising, before the step of laminating the frontal panel to the display face side of the display panel, a step of applying an adhesive for adhesively fixing the bezel and the frontal panel in the surface of the bezel opposing to the frontal panel and outer circumference of the first resin member and the second resin member.
