Abstract:
A liquid crystal display having high transmittance and high aperture ratio comprising:an upper and a lower substrate opposed to be spaced apart; a liquid crystal layer interposed between inner surfaces of the upper and lower substrates, the liquid crystal layer including a plurality of liquid crystal molecules; a gate bus line and a data bus line formed in the lower substrate in a matrix configuration and defining sub-pixel regions; a counter electrode of a rectangular plate shape formed at a sub-pixel region; a pixel electrode including a first electrode formed to be overlapped with a selected portion of the counter electrode, and a second electrode being extended from the first electrode in the form of a diagonal line; a thin film transistor formed at an intersection of the gate bus line and the data bus line, and switching a signal transmitted from the data bus line into the pixel electrode when the gate bus line is selected; and a homogeneous alignment layer formed on inner surfaces of the upper and lower substrates, wherein the second electrode within a selected sub-pixel region extended as a diagonal line of the gate bus line and the data bus line, wherein the second electrode within other sub-pixel regions adjoining in all directions to the selected sub-pixel region is arranged to make a symmetry with the selected sub-pixel region, wherein the counter and pixel electrodes are made of a transparent conductor.
