Abstract

A liquid crystal display device includes: LEDs; a liquid crystal panel; a flexible board connected to the liquid crystal panel; a driver mounted on the flexible board; a frame that has a frame section that has a frame-like shape and that holds the liquid crystal panel, and a side wall that extends from the edge of the frame section to the side opposite of a display surface side; and a source driver holder that holds the flexible board to the frame, and that has a first holding section that is disposed along the frame section and of which a portion is attached to the frame section and a second holding section that extends from the edge of the first holding section to the side opposite of the side of the display surface side.

First claim

1 . A display device, comprising:
a light source; a display panel that performs display by using light from the light source; a flexible board that has one end connected to the display panel; a driving part that is mounted on the flexible board and that drives the display panel; a frame having a frame section that holds the display panel by pressing on an edge on a display surface side of the display panel, and a side wall that extends from an edge of the frame section toward a side of the display device that is opposite to the display surface side; and a holding member that holds the flexible board with respect to the frame, the holding member having a first holding section that is disposed along the frame section, the first holding section having a portion that is attached to the frame section, and a second holding section disposed along the side wall of the frame and extending from an edge of the first holding section toward the side of the display device that is opposite of the display surface side.

2 . The display device according to claim 1 , further comprising:
a signal transmission substrate that is connected to another end of the flexible board and that transmits signals to the driving part, wherein said signal transmission substrate is disposed between said side wall of the frame and said second holding section.

3 . The display device according to claim 1 , wherein said first holding section, by having a wide region and a narrow region, does not overlap the driving part in a thickness direction of the flexible board.

4 . The display device according to claim 3 ,
wherein said first holding section is configured such that a plurality of the wide regions and a plurality of the narrow regions are alternately disposed, and wherein said first holding section has a spanning section that spans a gap between the wide regions that are adjacent to each other.

5 . The display device according to claim 1 ,
wherein said flexible board is provided in a plurality, wherein the portion of the first holding section that is attached to the frame is a protrusion that protrudes toward the frame, and wherein said protrusion is disposed between two of the flexible boards that are adjacent to each other.

6 . The display device according to claim 1 , further comprising:
a light guide plate that has a light-receiving face disposed on at least one end face of the light guide plate, the light-receiving face receiving light from said light source, and a light-exiting surface disposed on one surface of the light guide plate so as to face the display panel, wherein at least a portion of said first holding section of the holding member is disposed so as to be on a light-exiting surface side of the light source overlapping with the light guide plate in a plan view, and wherein said portion of the first holding section has such a thickness so as to abut an edge of the light-exiting surface of the light guide plate adjacent to the light-receiving face.

7 . The display device according to claim 6 , wherein the portion of the first holding section that protrudes toward the light source has light-reflective properties.

8 . The display device according to claim 1 , further comprising:
a light source substrate upon which a plurality of the light sources have been mounted; and a heat-dissipating member to which the light source substrate is attached, wherein the second holding section of the holding member abuts a portion of the heat-dissipating member.

9 . The display device according to claim 8 ,
wherein said portion of the heat-dissipating member is attached to said second holding section, and wherein said heat-dissipating member is separated from the frame.

10 . The display device according to claim 8 , further comprising:
a chassis that is disposed on a side opposite of the frame so as to face the holding member and that has at least a bottom plate, wherein said heat-dissipating member has a light source attachment section to which the light source substrate is attached and a heat-dissipating section that extends in parallel in a plate-like shape from an edge of the light source attachment section to the bottom plate, and wherein an entire surface of said heat-dissipating section abuts the bottom plate.

11 . The display device according to claim 1 ,
wherein said flexible board is provided in a plurality, wherein said plurality of flexible boards comprise a source side flexible board that is connected to one edge of the display panel and a gate side flexible board disposed on another edge of the display panel, and wherein said holding member is disposed in plurality so as to respectively hold the source side flexible board and the gate side flexible board with respect to said frame.

12 . The display device according to claim 1 , wherein said display panel is a liquid crystal panel that uses liquid crystal.

13 . A television receiver, comprising:
the display device according to claim 1 .
