摘要： 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 of the upper substrate and disposed at a location corresponding to the data bus line of the lower substrate; and a liquid crystal layer sandwiched between the upper and the lower substrates, wherein when the gate bus line is not selected, the shielding electrode forms an electric field with the data bus line.

摘要： Disclosed is a method of manufacturing a fringe field switching mode liquid crystal display device which can simplify process by reducing mask number. According to the present invention, a first transparent metal layer and a first metal layer are sequentially deposited on a transparent insulating substrate and patterned using a first mask. Next, a gate insulating layer, an amorphous silicon layer and a silicon nitride layer are sequentially deposited on the overall substrate and the silicon nitride layer is patterned using a second mask. The pattern portion is then patterned using a third mask so as to be exposed in the shape of a plate. Thereafter, a doped amorphous silicon layer and a second metal layer are sequentially deposited on the overall substrate and the second metal layer is patterned using the fourth mask. The doped amorphous silicon layer and the amorphous silicon layer are then etched using the source and drain as a mask. Next, a passivation layer is formed on the overall substrate and etched so as to expose a portion of the source. Thereafter, a second transparent metal layer is deposited on the passivation layer so as to fill the contact hole and patterned using a sixth mask.
