Patent ID: 7342621

Claim:
A thin film transistor substrate for a liquid crystal display, comprising: an insulating substrate; a black matrix formed on the insulating substrate having apertures in areas of pixels, which are provided in a matrix, such that the black matrix resembles a net; an insulating layer covering the black matrix; gate wiring formed on the insulating layer, the gate wiring including gate lines extended in a first direction across the substrate and gate electrodes connected to the gate lines; a gate insulating layer formed over the gate wiring; a semiconductor layer formed over the gate insulating layer; an ohmic contact layer formed over the semiconductor layer; data wiring including source electrodes and drain electrodes formed separated from each other over the ohmic contact layer and data lines connected to the source electrodes and crossing the gate lines to define pixels; a protection layer formed over the data wiring; pixel electrodes electrically connected to the drain electrodes; and apertures of the pixel electrodes or protrusions to form a fringe field or control a pretilt such that the liquid crystal molecules are slanted in various directions.
