Abstract
The present invention relates to a display device with a color filter used as an electrode which improves both color purity and optical efficiency of the display device and a method for manufacturing the same. The display device with color filters used as electrodes in accordance with the present invention is achieved by forming conductive color filters on an upper substrate. The fabrication process is simple and accordingly the production yield is increased for thereby reducing the manufacturing cost. In addition, the light transmittance and optical efficiency are increased, and the color purity is increased and external light reflection is effectively shut off.
