Patent ID: 7358945

Claim:
A liquid crystal display comprising a plurality of pixel areas, each comprising: a first substrate and a second substrate disposed opposite each other with a liquid crystal layer interposed therebetween; a first pixel electrode and a first thin film transistor formed on part of the first substrate, wherein the first pixel electrode is electrically connected to the first thin film transistor; a second pixel electrode and a second thin film transistor formed on part of the first substrate, wherein the second pixel electrode is electrically connected to the second thin film transistor; and a common electrode formed on an interior of the second substrate; wherein the first and second thin film transistors have mutually different ON currents (I on ), causing the first and second pixel electrodes to have mutually different voltages, and the first and second thin film transistors comprise the same gate, the same channel layer and the same source, wherein the first thin film transistor comprises a first drain with a first width “W 1 ” that is electrically connected to the first pixel electrode, the second thin film transistor comprises a second drain with a second width “W 2 ” that is electrically connected to the second pixel electrode, a first interval “L 1 ” exists between the first drain and the source, a second interval “L 2 ” exists between the second drain and the source and a relationship between W 1 , W 2 , L 1 and L 2 satisfies W 1 /L 1 ≠W 2 /L 2 .
