Abstract
Disclosed is a color liquid crystal display device having a plurality of pixels, in which conductive films are arranged at regions corresponding to the respective pixels, a light-shielding conductive layer is connected to the conductive films and extends in a region between the pixels, and color filters are formed on the conductive films. In the method of manufacturing such color liquid crystal display device, a light-shielding conductive layer is formed on a substrate, part of the light-shielding layer corresponding to a pixel for which a filter is to be formed is removed from the substrate on which the light-shielding layer is formed and simultaneously the light-shielding layer is partially removed so that portions thereof corresponding to at least pixels having different colors are electrically insulated from each other, a conductive film is formed at a portion corresponding to the pixel for which the filter is to be formed, and films having colors corresponding to those of the respective pixels are formed on the surface of the conductive film.
