Liquid crystal display on silicon device and its fabrication method

A method of manufacturing a liquid crystal display, comprising the steps of:

• (a) preparing a silicon wafer substrate;
• (b) forming driving circuits and active switching elements on said silicon wafer substrate;
• (c) forming a reflective pixel electrode layer having a plurality of pixel electrodes on said silicon wafer substrate with a pixel electrode gap between every two adjacent pixel electrodes, said active switching elements controlling voltages applied to said pixel electrodes;
• (d) depositing an insulating layer on said pixel electrode layer;
• (e) forming a common electrode layer on said insulating layer, said common electrode layer having a plurality of first common electrodes each being formed above a pixel electrode gap;
• (f) printing an alignment film on said common electrode layer;
• (g) preparing an upper glass substrate having a lower surface printed with an alignment film printed;
• (h) positioning said upper glass substrate above said silicon wafer substrate;
• and
• (i) forming a liquid crystal layer filled with negative type liquid crystals between said two alignment films.
