ABSTRACT:
A method of manufacturing an in-plane switching mode liquid crystal display device includes forming an insulation layer on a substrate, patterning a resist layer on the insulation layer, etching the insulation layer to form an insulation layer pattern having tapered edges, forming electrode layers on exposed surfaces of the substrate, the tapered edges, and the resist layer, etching the electrode layers formed on the exposed surfaces and on the resist layer, and removing the resist layer to form the common electrode and the pixel electrode with slopes and that are arranged parallel to each other on the tapered edges of the insulation layer. The common electrode and the pixel electrode each have a width less than 1 μm, which increases aperture ratio and transmittance.
