Abstract

A liquid crystal display device includes a liquid crystal panel, a backlight, a frame having flexibility which includes a base portion and a side portion, and a case which is attached on a side opposite to the display surface side of the frame and engages with the frame, wherein a claw portion which is provided on an inner surface of the side portion of the frame and projected toward a liquid crystal panel and, a protruding portion which pushes the claw portion toward the liquid crystal panel is provided on at least one of the inner surface of the side portion of the case and an outer surface of the side portion of the frame, and the claw portion which is contact with the display surface of the liquid crystal panel in a state in which the claw portion is pressed by the protruding portion.

Claims (18)

1. A liquid crystal display device comprising:

a liquid crystal panel;

a backlight which is attached to the liquid crystal panel;

a frame having flexibility which includes a base portion that holds the backlight and a side portion that surrounds a side surface of the liquid crystal panel fixed to a display surface side of the base portion; and

a case which engages with the frame, wherein

a claw portion which is provided on an inner surface of the side portion of the frame and projected toward a liquid crystal panel and,

a protruding portion which pushes the claw portion toward the liquid crystal panel is provided on at least one of the inner surface of the side portion of the case and an outer surface of the side portion of the frame, and

the claw portion which is contact with the display surface of the liquid crystal panel in a state in which the claw portion is pressed by the protruding portion.

2. The liquid crystal display device according to claim 1 , wherein the liquid crystal panel includes:

a glass substrate;

a polarizer which is disposed to the display surface of the glass substrate and whose outer size is smaller than that of the glass substrate; and

the claw portion is formed so that an end thereof is brought into contact with the display surface of the glass substrate on an outer circumference of the polarizer in a state in which the claw portion is pressed.

3. The liquid crystal display device according to claim 1 , wherein the liquid crystal panel includes:

the first glass substrate disposed to the display surface; and

the second glass substrate disposed to the rear surface whose outer size is larger than that of the first glass substrate, and

the claw portion is formed so that an end thereof is brought into contact with the display surface of the second glass substrate on an outer circumference of the first glass substrate in a state in which the claw portion is pressed.

4. The liquid crystal display device according to claim 1 , wherein the claw portions are disposed at positions facing with each other on an inner surface of the side portion of the frame.

5. The liquid crystal display device according to claim 4 , wherein a distance between the ends of the claw portions that face with each other is larger than the outer size of the display panel in a state in which the case has not been assembled.
