Abstract

A fringe-field-driven homogeneously aligned liquid crystal (LC) [named fringe-field switching (FFS) mode] microdisplay which is free of disclination lines has been designed. With a pixel structure newly proposed in which the LCs with negative dielectric anisotropy aligns perpendicular to the horizontal field existing between pixels and the equipotential area is optimized, the LC director is not deformed at all by this disturbing field between pixels. Consequently, the disclination lines can be suppressed even with a distance of 1 μm for a pixel size of about 15 μm so that a high resolution and high contrast microdisplay can be realized.
