Abstract
A liquid crystal display device and method that are adaptive to compensate for brightness deviation among red, green and blue colors. This device includes red liquid crystal cell lines having red liquid crystal cells, green liquid crystal cell lines having green liquid crystal cells, and blue liquid crystal cell lines having blue liquid crystal cells. Common electrodes are formed for each red, green and blue liquid crystal line. A common electrode of at least one liquid crystal cell line of the red, green and blue liquid crystal cell lines is supplied with a different common voltage that is a reference voltage to drive the liquid crystal cells.

A method of driving a liquid crystal display including red liquid crystal cell lines having red liquid crystal cells, green liquid crystal cell lines consisting of green liquid crystal cells and blue liquid crystal cell lines having blue liquid crystal cells, comprising:
- forming common electrodes for each red, green and blue liquid crystal line;
- and
- 1supplying a common voltage to at least one liquid crystal cell line of red, green and blue liquid crystal cell lines via the common electrode lines,
- wherein the common voltage of the at least one liquid crystal cell line is a different value from a common voltage supplied to remaining crystal cell lines, and
- wherein said common voltage is a reference voltage when driving the liquid crystal cells.
The method according to claim 1 1, wherein each of the red, green and blue liquid crystal cell lines is supplied with an independent common voltage.
