ABSTRACT:
An embodiment of the present invention discloses a Liquid Crystal on Silicon (LCOS) display unit, in which a Metal-Insulator-Metal (MIM) capacitor consisting of a micromirror layer, a insulation layer and a light shielding layer is formed by grounding the light shielding layer on a pixel switch circuit layer. Therefore the pixel switch circuit and the capacitor are in vertical distribution, that is, the switch circuit and the capacitor both have an allowable design area of the size of one pixel. Another embodiment of the present invention provides a method for forming a Liquid Crystal on Silicon (LCOS) display unit.
