Abstract

A liquid crystal apparatus includes a liquid crystal display panel including two substrates with liquid crystal interposed therebetween, a conductive layer provided on an outer surface of at least one of the substrates, a flexible board electrically connected to the liquid crystal display panel, and a tape-like conductive member providing an electrical connection between the conductive layer and a grounding wire of the flexible board.

Claims (15)

1. A liquid crystal apparatus comprising:

a liquid crystal display panel including two substrates with liquid crystal interposed therebetween;

a conductive layer provided on an outer surface of at least one of the substrates;

a flexible board electrically connected to the liquid crystal display panel; and

a tape-like conductive member providing an electrical connection between the conductive layer and a grounding wire of the flexible board,

wherein one of the two substrates has an extended portion extending beyond the other substrate, the extended portion having a surface provided thereon with a driver circuit and the flexible board,

wherein the tape-like conductive member is disposed across a region having the driver circuit, and

wherein at least a region where the driver circuit and the tape-like conductive member overlap each other is covered with an insulator.

2. The liquid crystal apparatus according to claim 1 , wherein the extended portion is provided with a grounding wire electrically connected to the grounding wire of the flexible board, and

wherein the tape-like conductive member provides an electrical connection between the conductive layer and the grounding wire of the extended portion.

3. The liquid crystal apparatus according to claim 1 , wherein the conductive layer includes a conductive optical sheet.

4. The liquid crystal apparatus according to claim 1 , wherein the conductive layer includes a transparent conductive film provided on the outer surface of the at least one of the substrates.

5. The liquid crystal apparatus according to claim 1 , wherein the liquid crystal display panel includes a common electrode and pixel electrodes provided on one of the two substrates, and

wherein the conductive layer is provided on an outer surface of the other substrate not having the common electrode and the pixel electrodes.

6. An electronic apparatus comprising the liquid crystal apparatus according to claim 1 as a display unit.
