摘要： PROBLEM TO BE SOLVED: To easily arrange the axis in the axisymetric orientation in a desired position and to obtain a liquid crystal display element having a stable wide visibility display mode by forming a recess corresponding to the area having a low conductivity in each color layer. SOLUTION: A conductive layer such as an ITO film or NESA film is formed all over a transparent substrate 1 such as a glass substrate and then patterned into conductive layers (transparent electrodes) 2 of a desired shape insulated from each other by photolithographic method or the like. Then a region having low conductivity, namely, a through hole 3 is formed in the conductive layer 2 for electrodeposition. This hole is preferably formed, for example, to have a square, circular or oval plan view. Then a black matrix (light-shielding layer) 4 is formed and color layers (R, G, B) are formed by electrodeposition. In the electrodeposition process, the substrate 1 having the light-shielding layer 4 formed like a window frame and the lower conductive layer 2 exposed like a window is used as one electrode, and this substrate and a counter electrode are both dipped in an electrodeposition liquid to perform electrodeposition.

SOLUTION: Colored coating films 1 having prescribed patterns are formed on a transparent substrate 3 and a light shielding film forming material is applied over the entire surface so as to fill the gaps between these colored films 1 and to coat the colored coating films 1. The applied entire surface is cured to form the light shielding film 2. The light shielding film 2 is then removed successively from its upper layer down to the lower layer and at least the light shielding film on the colored coating films is removed, thereby, the color filter is produced.
