ABSTRACT:
A video projector utilizes a reflective liquid crystal light valve of the active matrix system and a polarizing beam splitter. An active matrix array circuit of the light valve has pixel electrodes arranged in a matrix mattern. The pixel electrodes each has a reflective surface for reflecting a light beam and protects corresponding switch elements from the light beam. There are provided at least two switch elements for each of the pixel electrodes so as to enhance the redundancy of the array circuit. Further, each pixel electrode is provided with a suitable additional capacitance.
