ABSTRACT:
An object of the invention is to economically and easily form light-shielding means with high accuracy. An ITO film, which is used as transparent electrodes, and a resist layer are formed in this order on a surface of a light-transmitting substrate defining an X-Y plane. Thereafter, the resist layer is exposed, using a mask having a pattern corresponding to the transparent electrodes and developed. The bared ITO film is etched in a Z-direction to form the transparent electrodes. Then the light-shielding means is formed, by the use of an electrodeposition method, in a direction parallel to the insulating substrate, starting from a side surface of the transparent electrode not covered by the resist layer. After the completion of forming the light-shielding means, the resist layer on the transparent electrodes is removed. Thus, the steps of manufacturing the light shielding means are simplified.
