ABSTRACT:
A liquid crystal display element has pairs of light-shielding electrode films, each pair of which are selectively placed without contact with each other between adjacent transparent electrodes on one of the paired substrates along the long sides of each transparent electrode with overlapping portions with the long sides. The light-shielding electrode films have a conductivity, and are effective to reduce the resistance of the transparent electrodes. It also has wall-shaped spacers with a uniform height, each of which is formed between the adjacent transparent electrodes so as to have overlapping portions with the respective light-shielding electrode films. Here, the spacers have an insulating property and a light-shielding property. Moreover, the other portions except for the pixel aperture sections are shielded from light by either the light-shielding electrode films, the spacers, or black matrixes installed on the other substrate. Here, the black matrixes are installed at positions where none of the transparent electrodes, light-shielding electrode films and spacers are formed.
