Abstract

A display device includes a display with a display surface on which to display images, optical sources acting as a backlight to output light to the display, a diffuser panel disposed so as to face the optical sources, diffusing the light output from the optical sources, and a support pin disposed on the side opposite to the display across the diffuser panel. The support pin is contactable with the diffuser panel, maintains the position of the diffuser panel, and has a wide-width surface and a narrow-width surface that differ in width in two directions perpendicular to an alignment direction in which the display and the diffuser panel are aligned. The optical sources and the support pin are disposed alongside in a direction perpendicular to the alignment direction, and the narrow-width surface of the support pin faces the optical source at the shortest distance.

Claims

1. A display device comprising:

a display with a display surface on which to display an image;

a plurality of optical sources acting as a backlight to output light to the display;

a diffuser panel disposed so as to face the plurality of optical sources, the diffuser panel diffusing the light output from the optical sources; and

a support pin disposed on a side opposite to the display across the diffuser panel, the support pin being contactable with the diffuser panel and maintaining a position of the diffuser panel, wherein

the support pin has a wide-width surface and a narrow-width surface that differ in width in two directions perpendicular to an alignment direction in which the display and the diffuser panel are aligned,

the plurality of optical sources and the support pin are disposed alongside in a direction perpendicular to the alignment direction, and

the narrow-width surface of the support pin faces the optical source at a shortest distance.

2. The display device according to claim 1, wherein

two narrow-width surfaces are formed so as to face in opposite directions, each of the two narrow-width surfaces being the above narrow-width surface, and

the support pin is disposed between two optical sources.

3. The display device according to claim 2, wherein

the support pin is disposed in a center between the two optical sources.

4. The display device according to claim 1, wherein

a tip surface, which is part of an external surface of the support pin and located at an end on a diffuser panel side, is formed in a convex curved surface shape on the diffuser panel side.

5. The display device according to claim 1, wherein

the external surface of the support pin is formed in a curved surface shape.
