Abstract
A color filter substrate manufacturing method includes the steps of forming a black matrix having a plurality of first apertures of the same shape on a support substrate, forming a color filter by an ink jet system, and forming an alignment mark within an effective display region. The alignment mark includes a second aperture different in shape from the first apertures of the black matrix and is used to form the color filter.
