Abstract: A color liquid crystal display device comprises first and second transparent substrates, and a liquid crystal sealed therebetween. A plurality of display electrodes and thin film transistors each connected to each of the display electrodes are formed on the first transparent substrate. Color filters are formed on the second transparent substrate such that they each face each of the display electrodes. A common electrode is also formed over the entire surface of the second transparent electrode. The gap between adjacent color filters is closed by a metal layer capable of blocking light. These light-blocking layers overlie the common electrode in contact therewith.

Abstract: A liquid crystal display device is disclosed, which comprises first and second transparent substrates facing each other, a liquid crystal sealed between the transparent substrates, a plurality of display electrodes formed on the inner surface of the first transparent substrate, thin film transistors also formed on the first transparent substrate inner surface and each connected to each display electrode, and a transparent common electrode formed on the inner surface of the second transparent substrate, and in which the thin film transistors are selectively controlled to selectively drive the display electrodes for display. The resistance of semiconductor layers of the thin film transistors is reduced by external light to result in deterioration of the contrast of display. According to the invention, an opaque metal layer is formed between each thin film transistor and the first transparent substrate, and an insulating film is provided between the opaque metal layer and thin film transistor.
