Liquid crystal display device

Abstract

An IPS (In-Plane Switching) liquid crystal display is disclosed that maintains excellent display uniformity and high aperture ratio as well as high yield during fabrication, and that includes a first transparent substrate, a second transparent substrate arranged to confront the first transparent substrate and provided with a second alignment layer, and a liquid crystal component sealed between the first transparent substrate and second transparent substrate. The first transparent substrate is provided with: a transparent insulating substrate, pixel electrodes and common electrodes that are arranged alternately and substantially parallel to each other on the transparent insulating substrate, a plurality of pixels arranged in matrix form, scan lines and switching elements for controlling the electric field applied to the pixel electrodes, signal lines, and a first alignment layer. The direction of initial orientation of liquid crystal molecules in the aperture regions has an inclination of any angle θ other than 0° and 90° with respect to the longitudinal direction of the pixel electrodes. In regions other than the aperture regions, the direction of initial orientation of the liquid crystal molecules is orthogonal to the longitudinal direction of the pixel electrodes when the dielectric constant anisotropy of the liquid crystal molecules is positive, and parallel to the longitudinal direction of pixel electrodes when the dielectric constant anisotropy is negative.
