ABSTRACT:
A color liquid crystal display device is constituted by a first substrate having thereon a plurality of scanning electrodes, a second substrate disposed opposite to the first substrate and having thereon a plurality of data electrodes intersecting the scanning electrodes, a liquid crystal disposed between the scanning electrodes and the data electrodes, and color filter segments of at least three colors including red, green and blue disposed so as to form color display pixels each at an intersection of the scanning electrodes and data electrodes. The color filter segments of at least three colors respectively comprise a colored resin segment and are disposed on one of the first and second substrates having fewer electrodes thereon. As a result, the occurrence of defects, such as inclusion of foreign matter leading to short circuit between adjacent electrodes, during the color filter production step can be minimized, thus providing an improved product yield as a whole.
