Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPH04293018
Kind Code:
A
Abstract:
PURPOSE:To decrease the parasitic capacity generated between a picture element electrode and a data electrode, and a gate electrode and also reduce the generation of crosstalk and a halftone display error by making the corner parts of the picture element round, specially, circular. CONSTITUTION:The liquid crystal display device is formed in sandwich structure wherein two substrates which each have an electrode and an orienting film formed of a high polymer film of polyimide thereupon are combined, and one substrate is provided with the picture element electrode 3, data electrode, and gate electrode 2 as electrodes. The picture element electrode 3 is formed in a nearly rectangular shape having four corners made round and the picture element electrode 3 is formed circularly. Thus, the corner parts of the picture element electrode 3 are made round, specially, circular, so the corner parts of the picture element 3 are reduced in parasitic capacity, the parasitic capacity between the picture element electrode 3 and data electrode 1, and gate electrode 2 is reduced, and the generation of the crosstalk, half-tone display error, etc., is reducible.
