ABSTRACT:
A liquid crystal matrix display which uses a parallel pair of oppositely-poled diodes in series with the crystal element between the scanning and data electrodes. A circuit arrangement for combining the scanning electrodes, the pixel electrodes and the diodes on a common glass substrate uses insulating layers, opaque metallic layers, and transparent conductive layers in a manner to improve the aperture ratio of the display and to reduce the number of layers needed.
