Abstract

A liquid crystal display device is provided that prevents the cracking of a display panel without an increase in size. The liquid crystal display device includes a liquid crystal display panel, a cover plate arranged to face a surface of the liquid crystal display panel on which an image is displayed, and a backlight arranged to face a back surface of the liquid crystal display panel. The backlight includes a frame facing a peripheral part of the back surface of the liquid crystal display panel. The liquid crystal display panel has a planar shape in which at least one corner part of a rectangle is cut away. The frame includes a columnar part which rises in a direction toward the cover plate and fits in an area where the at least one corner part is cut away.

Claims (38)

1. A liquid crystal display device comprising:

a liquid crystal display panel; a cover plate arranged to face a surface of the liquid crystal display panel on which an image is displayed; and

a backlight arranged to face a back surface of the liquid crystal display panel,

wherein

the backlight includes a frame facing a peripheral part of the back surface of the liquid crystal display panel,

the liquid crystal display panel has a planar shape in which at least one intermediate side is formed between a first side and a second side,

the intermediate side directly connects the first side and the second side,

a first angle between the intermediate side and the first side is larger than a right angle,

a second angle between the intermediate side and the second side is larger than a right angle, and

the frame includes a columnar part which rises in a direction toward the cover plate adjacent to the intermediate side.

2. The liquid crystal display device according to claim 1 , wherein

the liquid crystal display panel includes a first substrate facing the cover plate and a second substrate facing the backlight,

the first substrate and the second substrate overlap each other in a state where a part of the second substrate protrudes from the first substrate, and constitute the planar shape of the liquid crystal display panel, and

a portion of the second substrate protruding from the first substrate has the intermediate side.

3. The liquid crystal display device according to claim 2 , wherein the columnar part is higher than the first substrate.

4. The liquid crystal display device according to claim 1 , wherein

a light-shielding layer is provided on a surface of the cover plate facing the liquid crystal display panel,

the columnar part faces the light-shielding layer, and a protecting film is provided in an area of the light-shielding layer facing the columnar part.

5. The liquid crystal display device according to claim 4 , wherein the protecting film is made of a metal.

6. The liquid crystal display device according to claim 1 , wherein a specified gap is provided between a surface of the columnar and the cover plate.

7. A display device comprising:

a display panel;

a cover plate arranged to face a surface of the display panel on which an image is displayed; and

a frame arranged to face a back surface of the display panel and supporting the display panel,

wherein

the display panel includes a first substrate facing the cover plate and a second substrate facing the frame,

the display panel includes at least one cut-away part in which a corner part is cut away,

the frame includes a columnar part which is adjacent to the cut-away part and rises in a direction toward the cover plate in an area of the corner part,

a height of the columnar part is higher than a position of the surface of the display panel,

the second substrate includes a protrusion protruding from the first substrate, and

the cut-away part is provided in the protrusion.

8. The display device according to claim 7 , wherein the at least one cut-away part includes two cut-away parts are provided in the protrusion.

9. The display device according to claim 7 , wherein

a light-shielding layer is provided on a surface of the cover plate facing the display panel,

the columnar part faces the light-shielding layer, and

a protecting film is provided in an area of the light-shielding layer facing the columnar part.

10. The display device according to claim 9 , wherein the protecting film is made of a metal.

11. The display device according to claim 7 , wherein the columnar part has a surface facing the cover plate and a specified gap is provided between the surface of the columnar part and the cover plate.
