Description
technical field [0001] The invention relates to a liquid crystal display, in particular to an array substrate of a liquid crystal display. Background technique [0002] As a display method of liquid crystal displays, Twisted Nematic (TN) method has been widely used in the past, but this method has limitations on the viewing angle in terms of display principles. [0003] As a method for solving this problem, a transverse electric field method is known, such as an in-plane switching (In Plane Switching, IPS) method and a fringe field switching (Fringe Field Switching, FFS) method. In the transverse electric field method, a pixel electrode and a shared electrode are formed on the array substrate, and a voltage is applied between the pixel electrode and the shared electrode to generate an electric field substantially parallel to the array substrate, and the electric field on the surface substantially parallel to the array substrate is drive the liquid crystal molecules.
