SUBSTRATE FOR REFLECTION TYPE LIQUID CRYSTAL CELL, AND REFLECTION TYPE LIQUID CRYSTAL DISPLAY DEVICE USING THE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a substrate for a reflection type liquid crystal cell which shows no decrease in the reflectance and which does not require a sticking process of a reflection plate, by forming a rugged reflection layer having a rugged pattern and a reflection layer on the surface of a substrate opposite to the surface to be in contact with a liquid crystal layer. ;SOLUTION: A rugged reflection layer 9 having a rugged pattern and a reflection layer is formed on the surface of a substrate 5 opposite to the surface to be in contact with a liquid crystal layer. The rugged reflection layer 9 reflects the light entering at a specified angle to the normal line direction of the liquid crystal panel to produce a diffused state. In the production process of the reflection layer 9, the surface profile is transferred to the back side of the substrate where electrodes to drive the liquid crystal are to be formed, electrode films are formed, and the electrode pattern is formed in a photolithographic process, and finally the reflection layer 9 is formed. By this method, since the reflection layer 9 is directly formed on the substrate, decrease in the reflectance can be avoided and no adhesive is required. Thus, a process to stick a reflection plate to a liquid crystal panel is made unnecessary and the production yield can be improved.;COPYRIGHT: (C)2000,JPO
