Abstract

A liquid crystal display apparatus includes a backlight unit including a light guiding plate that includes a light emitting surface, a light source and a back cover that covers the light guiding plate and the light source and has an opening in a region thereof that faces the light emitting surface, a liquid crystal display panel including an array substrate provided to face the light emitting surface, a counter substrate and a liquid crystal layer, a frame-shaped case that covers a peripheral portion of the counter substrate and peripheral walls of the back cover, and an input device provided on the case to face the counter substrate and having an entry surface, wherein the back cover includes a plurality of projecting portions which project even the light emitting surface, face a side edge of the liquid crystal display panel, and support the input device via the case.

Claims (11)

1. A liquid crystal display apparatus, comprising:

a backlight unit including a light guiding plate that includes a light emitting surface, a light source arranged to face a side edge of the light guiding plate, a back cover that covers the light guiding plate and the light source and has an opening in a region thereof that faces the light emitting surface, and a frame-shaped front cover that covers a peripheral portion of the light emitting surface and faces the side edge of the light guiding plate, and further covers peripheral walls of the back cover;

a liquid crystal display panel including an array substrate provided to face the light emitting surface, a counter substrate arranged to face the array substrate with a gap therebetween and a liquid crystal layer held between the array substrate and the counter substrate;

a frame-shaped case that covers a peripheral portion of the counter substrate and the peripheral walls of the back cover; and

an input device provided on the case to face the counter substrate and having an entry surface,

wherein the back cover includes a plurality of projecting portions which project through openings formed in the frame-shaped front cover and a side edge of the liquid crystal display panel in a direction perpendicular to the light emitting surface, contact a back of the case that faces the input device, and support the input device via the case.

2. The liquid crystal display apparatus according to claim 1 , wherein the back cover has a rectangular shape, and

the projecting portions include at least one projecting portion on each side of the back cover.

3. The liquid crystal display apparatus according to claim 1 , wherein the back cover has a rectangular shape, and

the projecting portions include two or more projecting portions on each side of the back cover.

4. The liquid crystal display apparatus according to claim 1 , wherein a thickness of the back cover, a thickness of the front cover, and a thickness of the case are each in a range of 0.2 mm to 0.3 mm.
