ABSTRACT:
A liquid crystal color display panel using a mosaic color filter and a twisted nematic liquid crystal layer arranged between a pair of linear polarizers and driven by a mosaic array of dot electrodes. An auxiliary glass plate quite thin in thickness is bonded onto the mosaic color filter built on the inner surface of a transparent plate, and the mosaic array of dot electrodes is formed on the inner surface of the auxiliary glass plate. With this structure, the liquid crystal layer and the mosaic color filter are separated only by the extremely thin auxiliary glass plate, and, therefore, a color disregistration due to parallax is minimized. The fragile auxiliary glass plate is reinforced by the strong back transparent plate.
