Abstract

In a conventional reflective liquid crystal panel using a semiconductor substrate, since storage capacitors are formed on the surface of the substrate, with a small pixel size, a sufficient storage capacitor (50 to 100 fF) cannot be ensured, and a voltage necessary for driving a liquid crystal cannot be held. The reflective electrode of each of pixels serves as a conductive layer of one of a pair of electrodes which constitute a storage capacitor, and the other conductive layer of the storage capacitor is formed below the reflective electrode through an insulation film so that the other conductive layer is fixed at the predetermined potential.

Description

technical field [0001] The present invention relates to the structure of a reflective electrode-side substrate constituting a reflective liquid crystal panel, a liquid crystal panel constructed using the substrate, and an electronic device using the liquid crystal panel. Background technique [0002] In the past, as an ultra-small high-definition active matrix liquid crystal panel suitable for applications such as light valves of projectors, a thin-film transistor (TFT) using polysilicon was formed on a quartz substrate, and a pixel electrode was formed on top of it. Transmissive liquid crystal panels made of transparent electrodes have been put into practical use. In the transmissive liquid crystal panel using the above-mentioned TFT, the region of the TFT provided in each pixel and the wiring region constituting the gate electrode, source and drain electrodes for driving the TFT are not the transmissive region through which light is transmitted. As the resolution of the s...
