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.
