摘要：
A color filter substrate includes: a base substrate; a light-shield layer and a color filter layer provided on the base substrate; a plurality of columnar spacers, which are made of a resin and provided so as to stick out of the base substrate; and an undercoat layer, which is provided between the columnar spacers and the base substrate. The color filter layer includes a first type of color filter, a second type of color filter and a third type of color filter, which transmit light rays in mutually different colors. The undercoat layer is made of the same film as one of the first, second and third types of color filters and the light-shield layer. A portion of the undercoat layer, associated with a first one of the columnar spacers, has a different area and/or shape from another portion of the undercoat layer, associated with a second one of the columnar spacers. The first and second columnar spacers have mutually different heights.
