Abstract

The invention relates to a micro-reflection liquid crystal display. A break difference existing in the prior processing procedure of the prior TFT-LCD Array substrate and two optical compensation films which are perpendicular up and down on an optical slow axis are mainly utilized to clamp a liquid crystal box; and the most suitable phase difference value in a perpendicular polarizer compensation system is obtained by the axial difference between the optical slow axis of the optical compensation films and a long liquid crystal shaft and is matched with the starting and the closing of a liquid crystal voltage to achieve the display functions of the best dark state and the best bright state. Meanwhile, the best dark state can be obtained by the same driving voltage in a reflection mode or a penetration mode, and the favorable comparison and reflection effects can be achieved without adding processing procedures.
