To solve such a problem that when a black matrix, colored pixels of RGB, a transparent electrode and a photospacer are produced by a photolithographic method, the number of required photomasks becomes 6 to 7 plates and according as the size of mother glass becomes larger, a cost burden of photomasks becomes larger.

A color filter substrate is characterized in that, at the least, colored pixels 2, 3, 4, which are arrayed while leaving a space between the adjacent ones thereof and each of which has a normal taper-shaped sidewall, a transparent electrode layer 5, and the black matrix 9, which has photospacers 7, 8 in the upper part thereof in the positions of the left spaces, are layered on a substrate 1 in this order.
