Abstract
A color filter substrate is used in a display device including pixels arranged in columns and rows to define a matrix pattern. The color filter substrate includes a transparent substrate and coloring layers, including a first color filter layer, a second color filter layer and an light shielding layer, provided on the transparent substrate. The first and second color filter layers include a first color filter column and a second color filter column, respectively, each of which is arranged for an associated column of pixels. The light shielding layer includes an light shielding column, which is provided for a gap between two adjacent columns of pixels. In a gap between two pixels that are adjacent in a row direction, an intercolumnar overlap area, in which the light shielding column and at least one of the first and second color filter columns overlap each other, and an intercolumnar non-overlap area, in which the light shielding column is overlapped by neither the first nor the second color filter column, are defined, and the intercolumnar non-overlap area is defined so as to extend continuously in the row direction through the gap between the two adjacent pixels.
