Abstract

A display device includes a display panel having a top surface and a bottom surface on the opposite side of the top surface and displays an image on the top surface, and a cover member covers the bottom surface of the display panel. The display panel includes a detecting element for detecting an object approaching the top surface. Also, the cover member is adhered to the bottom surface via the adhesive layer.

First claim

What is claimed is:

1 . A display device comprising:
a display panel having a first surface and a second surface that is on an opposite side of the first surface, and displaying an image on the first surface; and a first member covering the second surface of the display panel, wherein the display panel includes a detecting element detecting an object approaching the first surface, and the first member is adhered to the second surface via an adhesive layer.

2 . The display device according to claim 1 ,
wherein the display panel includes a first polarizing plate provided on the first surface of the display panel, and the first polarizing plate is exposed.

3 . The display device according to claim 1 ,
wherein the display panel includes a second polarizing plate provided on the second surface of the display panel, and the first member is adhered to the second polarizing plate via the adhesive layer.

4 . The display device according to claim 1 , further comprising a third polarizing plate provided on an opposite side of the display panel with the first member being interposed between the third polarizing plate and the display panel.

5 . The display device according to claim 1 , further comprising a second member disposed opposite to the display panel,
the first member being interposed between the second member and the display panel, the second member being disposed along at least a part of an outer peripheral portion of the display panel in a plan view.

6 . The display device according to claim 5 ,
wherein the display panel is a liquid crystal display panel, and the display device further comprises a backlight disposed opposite to the first member, the second member being interposed between the backlight and the first member.

7 . The display device according to claim 1 ,
wherein the display panel includes a first substrate and a second substrate, and the first member is made of a material having a Young's modulus which is equal to or greater than a Young's modulus of the first substrate or which is equal to or greater than a Young's modulus of the second substrate.

8 . The display device according to claim 1 ,
wherein the first member is made of glass.

9 . The display device according to claim 1 ,
wherein the first member is made of plastic.

10 . The display device according to claim 1 ,
wherein the adhesive layer is formed of a resin film.

11 . The display device according to claim 5 ,
wherein the second member is a frame member having a rectangular frame shape in a plan view.

12 . The display device according to claim 3 ,
wherein a portion of the first member which overlaps the second polarizing plate in a plan view is adhered to the second polarizing plate by an entire surface of the portion.

13 . The display device according to claim 4 ,
wherein a portion of the first member which overlaps the third polarizing plate in a plan view is adhered to the third polarizing plate by an entire surface of the portion.

14 . The display device according to claim 1 , further comprising
a second member disposed opposite to the display panel, the first member being interposed between the second member and the display panel, the second member including:
a first component formed in a first region; and
a second component formed in a second region that is separated from the first region in a plan view.

15 . The display device according to claim 1 ,
wherein a second member is disposed opposite to the first member, a third member is disposed opposite to the first member, and the third member has a degree of elasticity lower than a degree of elasticity of the second member.

16 . The display device according to claim 1 ,
wherein a surface of the first member on an opposite side of a surface of the first member facing the display panel has a first region in which a second member is disposed and a second region in which an air layer is disposed.

17 . The display device according to claim 5 ,
wherein the second member includes: a first extension part extending in a first direction; a second extension part extending in a second direction intersecting the first direction; a third extension part extending in the first direction and separated from the first extension part in a plan view; and a fourth extension part extending in the second direction and separated from the second extension part in a plan view, and each of the first extension part, the second extension part, the third extension part, and the fourth extension part supports an outer peripheral portion of the display panel via the first member.

18 . The display device according to claim 17 ,
wherein the display panel includes a third substrate and a fourth substrate, each of the third substrate, the fourth substrate, and the first member is made of glass, and when a total of thicknesses of the third substrate, the fourth substrate, and the first member are represented as ‘a’ (mm), a distance between the second extension part and the fourth extension part is represented as ‘b’ (mm), and a distance between the first extension part and the third extension part is represented as ‘L’ (mm), L 3 /(4a 3 b)≦10000 is established.
