Abstract
A liquid crystal display of the active matrix type includes a plurality of row electrodes orthogonal with a row of column electrodes and between each crosspoint is included a series arrangement of a liquid crystal element and a non-linear resistance provided by a parallel pair of oppositely poled diodes. Each of the diodes is constructed to have its photosensitive layer shielded from ambient light by its two electrodes, one of which is larger in cross-section than the light-sensitive layer and the other of which wraps around the edges of the layer.
