Abstract
The invention provides a LCD including an insulating substrate; a plurality of first signal lines formed on the insulating substrate; a plurality of second signal lines crossing and insulated from the first signal lines; a plurality of thin film transistors (TFT) coupled with the first and second signal lines; and a plurality of pixels including a plurality of first sub-pixel electrodes coupled with the TFTs and a plurality of second sub-pixel electrodes capacitively coupled with the first sub-pixel electrodes, wherein the pixels include a red (R) pixel, a green (G) pixel, and a blue (B) pixel and a voltage ratio or an area ratio of the second sub-pixel electrode with respect to the first sub-pixel electrode is different among the R, G, and B pixels to improve a brightness ratio of R, G, and B components at a lateral position.
