ABSTRACT:
A plurality of electrodes having a light-transmitting property are formed in a striped pattern on one surface of an insulating substrate having a light-transmitting property. Then, light-shielding films are formed in such a manner that the light-shielding films are formed adjacent to the edges of each electrode along the long sides thereof, or at least one portion of each light-shielding film is made to overlap each edge of the electrode along one of the long sides thereof. Successively, light is applied from the back-surface side of the insulating substrate by using the light-shielding films and a photomask as masks so that spacers are formed in a state where they are self-aligned with respect to the light-shielding films.
