Title: Liquid crystal panel and production thereof
Inventor: YAMAZOE HIROSHI
IPC: G02F1/1343
Filed: 1990-07-12
Abstract: PURPOSE:To obtain a liq. crystal panel having superior display characteristics at a reduced cost by forming a specified metal conductor layer on a first or second substrate and filling a liq. crystal into the gap between both the substrates. CONSTITUTION:A group of beltlike electrodes 3, 4 insulated from each other is formed on the principal surface of a first or second substrate 1 or 2. This group of electrodes is a group of transparent electrodes and an In-Ni-Cu or In-Cu laminate or a single Cu layer is present on part of each of the transparent electrodes. The substrates 1, 2 are placed opposite to each other with a prescribed gap between the principal surfaces and a liq. crystal is filled into the gap.
