Back substrate and reflective liquid crystal display

Abstract

A back substrate and a reflective liquid crystal display are disclosed. The back substrate comprises: a first substrate; a reflective electrode layer, formed on the first substrate, at least comprising a first reflective electrode, a second reflective electrode and a third reflective electrode which are electrically isolated; wherein the first reflective electrode is an electrode of reflecting light of a first spectrum band of incident light, the second reflective electrode is an electrode of reflecting light of a second spectrum band of the incident light, and the third reflective electrode is an electrode of reflecting light of a third spectrum band of the incident light. The structures of the back substrate and the reflective liquid crystal display are simplified, the problems associated with inter-pixel color blur and degradation of optical efficiency owing to inaccurate alignment of pixelated color filter array film and the pixelated reflective electrodes, and electrical field drop from thick dielectric color filters can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of liquid crystal display, and in particular to a bottom substrate and a reflective liquid crystal display. Background technique [0002] In recent years, with the development of optoelectronic technology and integrated circuit technology, flat panel displays (especially liquid crystal displays) have become the mainstream of display devices. Compared with other monitors, liquid crystal monitors are light and thin in shape, small in weight, low in operating voltage, low in power consumption, full in color, and have low radiation. Liquid crystal displays can be classified into transmissive, reflective, and transflective. Reflective liquid crystal displays include liquid crystal projectors and reflective liquid crystal on silicon (LCOS for short). [0003] Liquid crystal displays generally include an upper glass substrate formed with a transparent conductive layer (usually a thin film fo...
