Patent ID: 7492428

Claim:
A thin film transistor array substrate, comprising: a gate line and a data line on a substrate to define a pixel area; a thin film transistor in the pixel area; a pixel electrode connected to the thin film transistor; and a common electrode positioned to oppose the pixel electrode and forming a plurality of columns and rows of closed aperture areas for transmitting and shutting off light by a rotation of liquid crystal positioned within said aperture areas, wherein the pixel electrode and the common electrode are configured such that an electric field between the pixel electrode and the common electrode in a first aperture area is substantially symmetric to an electric field between the pixel electrode and the common electrode in a second aperture area, wherein the first and second aperture areas include at least one of an acute or obtuse angle, and wherein the pixel electrode includes a plurality of horizontal parts parallel to the gate line and a vertical part connected to the plurality of horizontal parts and parallel to the data line.
