Abstract
The present invention is directed to provide a liquid crystal display having an improved picture quality, high transmittance and high aperture ratio.The liquid crystal display comprises: an upper and a lower substrate opposed each other 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 formed on each sub-pixel region of the lower substrate; a pixel electrode formed on each sub-pixel region of the lower substrate, wherein the counter electrode and the pixel electrode form an electric field; 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 a first electric field is formed between the counter and pixel electrodes of a selected sub-pixel among the s…
