Abstract

A liquid crystal device includes a pair of substrates between which liquid crystal is sandwiched, a plurality of pixel electrodes arranged in a matrix on one of the substrates, switching elements that control the supply of current to the pixel electrodes, scanning lines that supply scanning signals to the switching elements, and data lines that cross the scanning lines and that supply image signals to the switching elements. The pixel electrodes are arranged in pairs, and each pair of the pixel electrodes are adjacent in an extending direction of the data lines and are disposed between a corresponding pair of the scanning lines in the extending direction of the data lines. The switching elements corresponding to each line of the pixel electrodes arrayed in the extending direction of the data lines are alternately connected to either of opposing sides of an adjacent pair of the data lines in the extending direction of the data lines.

Claims (10)

1. A liquid crystal device comprising:

a pair of substrates between which liquid crystal is sandwiched;

a plurality of pixel electrodes arranged in a matrix on one of the substrates;

switching elements that control a supply of current to the pixel electrodes;

scanning lines that supply scanning signals to the switching elements; and

data lines that cross the scanning lines and that supply image signals to the switching elements, wherein

the pixel electrodes are arranged in pairs, each pair of the pixel electrodes being adjacent in an extending direction of the data lines and being disposed between a corresponding pair of the scanning lines in the extending direction of the data lines;

the scanning lines include a plurality of scanning lines that are stacked such as to coincide with each other in plan view; and

the pixel electrodes are arranged in first pairs and second pairs, each first pair of the pixel electrodes being adjacent in an extending direction of the data lines and being disposed between a corresponding pair of the scanning lines in the extending direction of the data lines, and each second pair of the pixel electrodes being adjacent in an extending direction of the scanning lines and being disposed between a corresponding pair of the data lines in the extending direction of the scanning lines.

2. A projector that performs light modulation with the liquid crystal device according to claim 1 .
