Liquid crystal display device with electrically discharged spacers

Abstract

A liquid crystal display device having high contrast ratio and high display quality which does not give any impression of roughness on display plane is provided. An amount of charges on the surface of spacers is made zero or almost zero, whereby brightness of a region where spacers are arranged is adjusted to be at most twice the brightness of that region where the spacers are not arranged in a black (dark) display state, with the spacers distribution density being 100 to 600 particles/mm2 and the spacers diameter being 2 to 6 μm. For this purpose, as the spacers for keeping constant a space between an electrode substrate and a counter substrate, those formed by an acrylate resin with its surface plated with gold and having surface specific resistance of 5 Ω·m and diameter of 6 μm are used. Further, the spacers may be distributed by using a spacer distributing apparatus having a spacer carrier pipe system formed of the same material as the surface material of the spacers.
