Abstract

A manufacturing method of a color filter including following steps is provided. First, a partition is formed on a substrate to form a plurality of pixel regions on the substrate. Next, a color pigment is provided along a continuous pigment-providing route, so as to form the color pigment on a sequence of pixel regions among the plurality of pixel regions and the partition. The method mentioned above can prevent the unfilled phenomenon of the pigment around the corners of the pixel region.
