Patent ID: 7499129

Claim:
A liquid crystal display, comprising: an insulating substrate; a plurality of first signal lines formed on the insulating substrate; a plurality of second signal lines crossing the first signal lines and insulated from the first signal lines; a plurality of thin film transistors coupled with the first signal lines and the second signal lines; and a plurality of pixels comprising a plurality of first sub-pixel electrodes coupled with the thin film transistors and a plurality of second sub-pixel electrodes capacitively coupled with the first sub-pixel electrodes, wherein pixels of the plurality of pixels comprise a red pixel, a green pixel and a blue pixel, the red pixel comprises a red first sub-pixel electrode and a red second sub-pixel electrode, the green pixel comprises a green first sub-pixel electrode and a green second sub-pixel electrode, and the blue pixel comprises a blue first sub-pixel electrode and a blue second sub-pixel electrode; and voltage ratios of the second sub pixel electrode with respect to the first sub-pixel electrode for each of the green pixel and the blue pixel are less than a voltage ratio of the second sub-pixel electrode with respect to the first sub-pixel electrode for the red pixel.
