Abstract
Disclosed is a liquid crystal display having high aperture ratio and high transmittance that is capable of reducing the size of a leakage light generating region.The present invention provides a liquid crystal display comprising: a lower substrate; a gate bus line and a data bus line, both disposed in an active matrix type so as to define a sub-pixel on the lower substrate; a counter electrode formed at the sub-pixel region of the lower substrate, made of a transparent material, wherein a common signal is applied to the counter electrode; a pixel electrode formed at the sub-pixel region of the lower substrate, made of a transparent material, wherein the pixel electrode forms a fringe field with the counter electrode; a thin film transistor formed at an intersection of the gate bus line and the data bus line, wherein when the gate bus line is selected, the thin film transistor transmits a signal of the data bus line to the pixel electrode; an upper substrate opposed to the lower substrate with intervening a selected distance; a black matrix formed at an inner surface of the upper substrate and arranged so as to define the sub-pixel; a shielding electrode formed at an inner surface o…
