Patent ID: 7929069

Claim:
A thin film transistor substrate for a liquid crystal display, comprising: an insulating substrate; a black matrix formed on said insulating substrate having apertures in areas of pixels and shaped as a net; an insulating layer covering said black matrix; a gate wiring formed on said insulating layer, said gate wiring including gate lines extended in a first direction across said substrate and gate electrodes connected to the gate lines; a gate insulating layer formed over said gate wiring; a semiconductor layer formed over said gate insulating layer; an ohmic contact layer formed over said semiconductor layer; a data wiring including source electrodes and drain electrodes formed separated from each other over said ohmic contact layer, and data lines connected to the source electrodes and crossing the gate lines to define the pixels; a protection layer formed over said data wiring; and pixel electrodes electrically connected to the drain electrodes, wherein the black matrix includes first portions parallel with the gate lines and each of the first portions is separated from each other.
