  • Publication number: 20210018779
    Abstract: A display device may include the following elements: a transistor; a pixel electrode electrically connected to the transistor; a first color filter overlapping the pixel electrode; a first color filtering member including a same material as the first color filter; a second color filter partially overlapping the first color filter or immediately neighboring the first color filter; a third color filter overlapping the first color filtering member and partially overlapping the second color filter or immediately neighboring the second color filter; a main spacer overlapping the third color filter; and an auxiliary spacer overlapping the first color filter or the second color filter and being shorter than the main spacer. The third color filter includes a first portion and a second portion. The first portion overlaps the first color filtering member. The second portion neighbors the first portion and is thicker than the first portion.
