ABSTRACT:
A color filter substrate includes a transparent substrate with first and second opposed edges, a color filter layer including color filters of first, second and third types extending in a first direction with the third type interposed between the first and second types, and an opaque layer including opaque portions extending in the first direction and another opaque portion connected to the other opaque portions along the second edge. The color filter substrate is fabricated by (a) forming the opaque layer on the transparent substrate, and then (b) forming the color filter layer thereon. The step (a) includes forming an opening in a non-effective display area of the color filter substrate between one end of each color filter of the third type and the second edge. The step (b) includes attaching and rolling a dry film in the first direction on the transparent substrate after the color filters of the first and second types have been provided thereon.
