Abstract: A display device includes a display panel including a plurality of pixels; and a color filter member on the display panel. The color filter member includes a partition member where a plurality of opening parts each overlapping with at least one of the plurality of pixels on a plane is defined, a liquid-repellent coating layer covering the partition member, and a color conversion member including a first color conversion pattern and a second conversion pattern, which are in each of the opening parts and provide different light. The first color conversion pattern includes a first bent part and a first color conversion part, which include the same material and contact each other to form an interface. The second color conversion pattern includes a second bent part and a second color conversion part, which include the same material and contact each other to form an interface.
