Abstract

A liquid crystal device includes: lower electrodes which are formed in an element substrate; an insulating film which is stacked on the lower electrodes; upper electrodes which are stacked on the insulating film and each provided with a slit for generating a fringe electric field; a counter substrate which is formed opposite the element substrate; liquid crystal which is interposed between the counter substrate and the element substrate; a shield electrode which is formed in a potentially floating state on an inner surface of the counter substrate opposed to the element substrate; and a resin layer which is formed on the inner surface of the counter substrate.

Claims (27)

1 . A liquid crystal device comprising:

lower electrodes which are formed in an element substrate;

an insulating film which is stacked on the lower electrodes;

upper electrodes which are stacked on the insulating film and each provided with a slit for generating a fringe electric field;

a counter substrate which is formed opposite the element substrate;

liquid crystal which is interposed between the counter substrate and the element substrate;

a shield electrode which is formed in a potentially floating state on an inner surface of the counter substrate opposed to the element substrate; and

a resin layer which is formed on the inner surface of the counter substrate.

2 . The liquid crystal device according to claim 1 , wherein the shield electrode and the resin layer are formed in order from the counter substrate on the inner surface of the counter substrate.

3 . The liquid crystal device according to claim 1 , wherein the resin layer and the shield electrode are formed in order from the counter substrate on the inner surface of the counter substrate.

4 . A liquid crystal device comprising:

lower electrodes which are formed in an element substrate;

an insulating film which is stacked on the lower electrodes;

upper electrodes which are stacked on the insulating film and each provided with a slit for generating a fringe electric field;

a counter substrate which is formed opposite the element substrate;

liquid crystal which is interposed between the counter substrate and the element substrate;

a shield electrode which is formed on an inner surface of the counter substrate opposed to the element substrate; and

a resin layer which is stacked next to the shield electrode from the counter substrate,

wherein a pixel electrode is formed of one of the lower electrode and the upper electrode and a common electrode is formed of the other thereof, and

wherein the shield electrode is opposed to the common electrode and a potential having an absolute value higher than that of a common potential applied to the common electrode and having the same polarity as that of the common voltage is applied to the shield electrode.

5 . The liquid crystal device according to claim 4 , wherein the shield electrode is electrically connected to a wire formed on the element substrate through an electric conductive member interposed between the element substrate and the counter substrate.

6 . The liquid crystal device according to claim 4 ,

wherein the common electrode and the shield electrode extend in a strip shape along pixels arranged in a horizontal direction or a vertical direction and are divided in a direction intersecting the extension direction, and

wherein different common potentials are applied to adjacent common electrodes.

7 . The liquid crystal device according to claim 2 , wherein the resin layer has a thickness of 2 μm or more and permittivity of 6 or less.

8 . The liquid crystal device according to claim 2 , wherein the resin layer includes a color filter layer.

9 . An electronic apparatus comprising the liquid crystal device according to claim 1 .
