Abstract

The present invention provides a color LCD, which comprises a first substrate and a second substrate with a liquid crystal layer sandwiched in between and a seal-ring for sealing them. The seal-ring has conductive spacers. Transparent electrode plates cover two opposed surfaces of the two substrates, respectively. The seal-ring having conductive spacers is used to conduct the two transparent electrode plates. A color filter is disposed between the first substrate and the transparent electrode plates. The color filter has a plurality of pixels disposed thereon. Each of the pixels comprises at least two sub pixels, and each of the sub pixels is composed of at least two colors. Conductive walking lines on the transparent electrode plates are used to electrically connect at least two data transmission lines of the same color in each column of longitudinally-arranged pixels to the same pin.
