## Abstract

A liquid crystal display device 10 includes LEDs 17, a liquid crystal panel 11, a chassis 14, a frame 13, positioning ribs 23, opposed portions 25, and gel members 30. The liquid crystal panel 11 is configured to display using light from the LEDs 17. The chassis 14 is arranged on an opposite side of the liquid crystal panel 11 from a display surface 11c that is for display. The frame 13 is arranged on the display surface 11c side of the liquid crystal panel 11. The frame 13 holds at least the liquid crystal panel 11 and the LEDs 17 with the chassis 14 such that the liquid crystal panel 11 and the LEDs 17 are sandwiched between the frame 13 and the chassis 14. The positioning ribs 23 project from the frame 13 toward the chassis 14. The positioning ribs 23 include a peripheral surface opposite a peripheral surfaced of the liquid crystal panel 11 for positioning the liquid crystal panel 11. The opposed portions 25 are arranged at portions opposite the positioning ribs 23 of the liquid crystal panel 11. The gel members 30 have elastic properties and are arranged in gaps between the positioning ribs 23 and the respective opposed portions 25.

## Claims

### Claim 1

A display device comprising:
a light source;
a display panel configured to provide a display using light from the light source;
a chassis arranged on an opposite side of the display panel from a display surface of the display panel;
a frame arranged on a display surface side of the display panel and holding at least the display panel and the light source between the frame and the chassis;
a first positioning portion projecting from the frame toward the chassis and including a peripheral surface opposite a peripheral surface of the display panel to position the display panel;
a second positioning portion included in the display panel in a portion thereof opposite the first positioning portion; and
an elastic member in a gap between the first positioning portion and the second positioning portion.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein the elastic member is in contact with the first positioning portion and the second positioning portion.

### Claim 3 (depends on 2)

The display device according to claim 2, wherein the elastic member is in a gel state.

### Claim 4 (depends on 1)

The display device according to claim 1, further comprising a light guide plate arranged over an opposite surface of the display panel to the display surface, including a peripheral surface opposite the light source, configured to guide the light from the light source toward the display panel, and including a cutout that receives the first positioning portion in the peripheral surface, wherein
the first positioning portion projects from the frame toward the chassis so as to face the peripheral surface of the light guide plate, and
the first positioning portion is fitted in the cutout.

### Claim 5 (depends on 4)

The display device according to claim 4, wherein
the elastic member has a light blocking property, and
the gap between the first positioning portion and the cutout is filled with the elastic member.

### Claim 6 (depends on 1)

The display device according to claim 1, wherein
the first positioning portion includes a protrusion that protrudes toward the display panel,
the second positioning portion includes a recess that opens toward the protrusion such that the protrusion is fitted therein, and
the elastic member is in the gap between the protrusion and the recess.

### Claim 7 (depends on 6)

The display device according to claim 6, wherein
the protrusion and the recess have rectangular shapes in a plan view, and
the elastic member is at least in a gap between a distal end surface of the protrusion and a bottom surface of the recess.

### Claim 8 (depends on 1)

The display device according to claim 1, further comprising multiple pairs of the first positioning portion and the second positioning portion.

### Claim 9 (depends on 8)

The display device according to claim 8, wherein
the multiple pairs of the first positioning portion and the second positioning portion are arranged at opposed sides of the display panel and opposed sides of the frame.

### Claim 10 (depends on 1)

The display device according to claim 1, wherein the display panel is a liquid crystal display panel including liquid crystals.

### Claim 11 (depends on 1)

A television device comprising the display device according to claim 1.
