Abstract
A driving circuit of a color liquid crystal display is provided which is capable of reducing a substrate packaging area and using a common substrate or TCP (Tape Carrier Package) even when a resolution and/or the number of gray scale voltages that the color liquid crystal display provides are different, which enables the substrate, TCP, and a display device to be fabricated at low costs. In the driving circuit of the color liquid crystal display, a data electrode driving circuit produces gray scale voltages corresponding to gray scale voltage characteristics based on serial data made up of gray scale information and gray scale voltage information.
