ABSTRACT:
A color electrooptical device includes a color filter substrate and a transparent substrate being spaced apart and facing each other. The color filter substrate has a color filter layer and a transparent electrode pattern and the transparent substrate has a transparent electrode pattern. Liquid crystal material is sealed between the two substrates through a sealing portion. A non-driving transparent electrode is interposed between the sealing portion and the color filter substrate and a non-driving transparent electrode is interposed between the sealing portion and the transparent substrate to provide and maintain a uniform cell gap between the two substrates. A method of manufacturing the color electrooptical device is also disclosed.
