Abstract: A display substrate includes a base substrate having a plurality of pixel areas and a pixel electrode in a pixel area of the plurality of pixel areas. The pixel electrode a first stem portion extending in a first direction, a second stem portion extending from the first stem portion in a second direction that intersects the first direction, a plurality of branch portions diagonally extending from at least one of the first stem portion and the second stem portion, and a bent portion extending from at least one of the plurality of branch portions.

Abstract: Provided is a color filter having improved light efficiency and color reproducibility. The color filter includes: a substrate having a plurality of pixel areas and a light blocking area surrounding the plurality of pixel areas; a light blocking layer on the light blocking area; a first color conversion layer on a first pixel area among the plurality of pixel areas and configured to convert incident light into light of a first color; a first color filter layer between the substrate and the first color conversion layer and configured to selectively transmit the light of the first color emitted from the first color conversion layer; and a light reflection layer between the first color conversion layer and the first color filter layer and including a reflective material.
