In-plane switching type liquid crystal display devices having improved aperture ratio and methods of fabrication therefor using nonuniform spacing between pixel and common electrodes

Abstract

A pixel is formed on a substrate for a panel of an LCD display, disposed adjacent a data line. The pixel includes a plurality of spaced apart elongate pixel electrodes extending parallel to the data line and a plurality of spaced apart elongate common electrodes extending parallel to the data line and interspersed among the pixel electrodes such that a respective pixel electrode is disposed adjacent a respective common electrode. The common and pixel electrodes define a plurality of gaps, a respective one of the gaps separating a common electrode and a pixel electrode, the plurality of gaps having nonuniform widths. Preferably, the plurality of gaps includes a first group of gaps having a first width and a second group of gaps having a second width. According to one embodiment, the first group of gaps includes all of the plurality of gaps except a gap between one common electrode nearest the data line and a pixel electrode nearest the one common electrode. According to another embodiment, the first group of gaps includes all of the plurality of gaps except a gap between a first common electrode nearest the data line and a pixel electrode nearest the first common electrode and a gap between a second common electrode furthest from the data line and a pixel electrode nearest the second common electrode.
