Claim:
A liquid crystal element, comprising: a multitude of pixel electrodes; a liquid crystal to which an electric field is applied by said pixel electrodes, said liquid crystal has such a structure that a four-sided minute pixel electrode is arrayed in a lattice in X, Y directions crossing each other at a right angle on a display plane and said non-conductive portion; an inclined structure, wherein an electric field direction of the liquid crystal between at least one pair of adjacent pixels is inclined against an electrode plane; and an opposite electrode parallel with said pixel electrodes, wherein the liquid crystal is held between said pixel electrodes and said opposite electrode, the inclined structure has a non-conductive portion provided in a part of the opposite electrode that is opposite to a gap between at least one pair of adjacent pixel electrodes; and a side of the pixel electrode is opposite to the opposite electrode, and the other side of the pixel electrode is opposite to the non-conductive portion, wherein, in view of a Z direction at a right angle with X, Y directions when a pixel of i-th position in X direction and j-th position in Y direction from an edge point or a standard point is defined as p (i, j), said non-conductive portion, comprises: a first nonconductive portion, with a rectangular shape having a longer side in Y direction and a larger width in X direction than a distance between a pixel p (4m, 4n+1) and a pixel p (4m+1, 4n+1), which includes an opposite electrode corresponding to each of at least a part of a gap between a pixel p (4m, 4n) [m, n: an integer] and a pixel p (4m+1, 4n) as well as at least a part of a gap between a pixel p (4m, 4n+1) and a pixel p (4m+1, 4n+1); a second nonconductive portion, with a rectangular shape having a longer side in X direction and a larger width in Y direction than a distance between a pixel p (4m+1, 4n+2) and a pixel p (4m+1, 4n+3), which includes an opposite electrode corresponding to each of at least a part of a gap between a pixel p (4m, 4n+2) and a pixel p (4m, 4n+3) as well as at least a part of a gap between a pixel p (4m+1, 4n+2) and a pixel p (4m+1, 4n+3); a third nonconductive portion, with a rectangular shape having a longer side in X direction and a larger width in Y direction than a distance between a pixel p (4m+2, 4n) and a pixel p (4m+2, 4n+1), which includes an opposite electrode corresponding to each of at least a part of a gap between a pixel p (4m+2, 4n) and a pixel p (4m+2, 4n+1) as well as at least a part of a gap between a pixel p (4m+3, 4n) and a pixel p (4m+3, 4n+1); and a fourth nonconductive portion, with a rectangular shape having a longer side in Y direction and a larger width in X direction than a distance between a pixel p (4m+2, 4n+3) and a pixel p (4m+3, 4n+3), which includes an opposite electrode corresponding to each of at least a part of a gap between a pixel p (4m+2, 4n+2) and a pixel p (4m+3, 4n+2) as well as at least a part of a gap between a pixel p (4m+2, 4n+3) and a pixel p (4m+3, 4n+3).
