Display device
View Patent ↗A display device according to an aspect of the present invention includes a cover member and a display panel. The cover member includes a base material and a light-shielding layer provided in a frame-like manner. A double-faced adhesive sheet is provided so as to cover the surface of the base material and an edge portion on an inner circumferential side of the light-shielding layer. A plurality of grooves not deep enough to penetrate the light-shielding layer are provided on the edge portion on the inner circumferential side of the light-shielding layer to which the double-faced adhesive sheet is bonded. The grooves extend from the inner circumference toward an outer circumference of the light-shielding layer. The grooves are arranged side by side along the inner circumference of the light-shielding layer.
1. A display device comprising a cover member and a display panel that are bonded to each other with a double-faced adhesive sheet, wherein
the cover member includes a base material and a light-shielding layer formed on a surface of the base material;
the light-shielding layer is provided in a frame-like manner in a position rimming a display area of the display panel;
the double-faced adhesive sheet is provided so as to cover the surface of the base material located in a region surrounded by the light-shielding layer and an edge portion on an inner circumferential side of the light-shielding layer;
the edge portion on the inner circumferential side of the light-shielding layer to which the double-faced adhesive sheet is bonded is provided with a plurality of grooves not deep enough to penetrate the light-shielding layer;
the grooves extend from the inner circumference toward an outer circumference of the light-shielding layer; and
the grooves are arranged side by side along the inner circumference of the light-shielding layer.
2. The display device according to claim 1 , wherein
each of the grooves is formed so as to be not long enough to reach the outer circumference of the light-shielding layer; and
ends of the double-faced adhesive sheet are bonded to the light-shielding layer on an outer circumferential side of the region where the grooves are formed.
3. The display device according to claim 1 , wherein
the light-shielding layer is formed into a rectangular frame shape; and
a space interval between adjacent ones of the grooves decreases as the position of the space interval is closer to each corner of the inner circumference of the light-shielding layer.
