Abstract

A liquid-crystal display device includes a display panel, a translucent cover substrate, and a plate spacer. The display panel includes a pixel substrate, a counter substrate facing the pixel substrate, a liquid-crystal layer interposed between the pixel substrate and the counter substrate, and a driver IC mounted on a protruding portion of the pixel substrate protruding from the counter substrate. The translucent cover substrate is bonded to the display panel. The plate spacer is formed in a rectangular plate shape and is fixed to a surface of the translucent cover substrate on the driver IC side. The plate spacer and the driver IC are fixed with a resin layer interposed therebetween.

Claims (25)

1. A liquid-crystal display device comprising:

a display panel including a pixel substrate, a counter substrate facing the pixel substrate, a liquid-crystal layer interposed between the pixel substrate and the counter substrate, and a driver IC mounted on a protruding portion of the pixel substrate protruding from the counter substrate;

a translucent cover substrate bonded to the display panel; and

a plate spacer formed in a rectangular plate shape and fixed to a surface of the translucent cover substrate on the driver IC side,

wherein the plate spacer is positioned so as to overlap the driver IC in a planer view,

wherein an optical functional film is bonded to a surface of the counter substrate, the surface being opposite to a surface of the counter substrate facing the pixel substrate, and

wherein a gap between the optical functional film and the translucent cover substrate, a gap between the counter substrate and the translucent cover substrate, a gap between the pixel substrate and the plate spacer, and a gap between the plate spacer and the driver IC are filled with a resin layer.

2. The liquid-crystal display device according to claim 1 , wherein the plate spacer has a size covering the driver IC in a planar view.

3. The liquid-crystal display device according to claim 1 , wherein the plate spacer has a translucent property, and the resin layer is an ultraviolet curing resin.

4. The liquid-crystal display device according to claim 1 , wherein an area of the optical functional film is smaller than that of the counter substrate.

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

the plate spacer is a first plate spacer,

the pixel substrate includes two second plate spacers, one of the second plate spacers being arranged on one side in the width direction of the driver IC, and another of the second plate spacers being arranged on another side in the width direction of the driver IC, and

the first plate spacer and the second plate spacer have portions facing each other.

6. An electronic apparatus comprising:

a liquid-crystal display device; and

an accommodating member housing the liquid-crystal display device, wherein

the liquid-crystal display device includes:

a display panel including a pixel substrate, a counter substrate facing the pixel substrate, a liquid-crystal layer interposed between the pixel substrate and the counter substrate, and a driver IC mounted on a protruding portion of the pixel substrate protruding from the counter substrate;

a translucent cover substrate bonded to the display panel; and

a plate spacer formed in a rectangular plate shape and fixed to a surface of the translucent cover substrate on the driver IC side,

wherein the plate spacer is positioned so as to overlap the driver IC in a planer view,

wherein an optical functional film is bonded to a surface of the counter substrate, the surface being opposite to a surface of the counter substrate facing the pixel substrate,

wherein a gap between the optical functional film and the translucent cover substrate, a gap between the counter substrate and the translucent cover substrate, a gap between the pixel substrate and the plate spacer, and a gap between the plate spacer and the driver IC are filled with a resin layer, and

wherein a part of the accommodating member presses the pixel substrate.
