Abstract
A display device including a substrate, a circuit portion including a thin film transistor on the substrate, a display element on the circuit portion, the display element including a pixel electrode electrically connected to the thin film transistor, an encapsulation layer covering the display element, a color filter layer on the encapsulation layer, the color filter layer including a black matrix and a color filter, and a light transmission control layer located farther from the display element than the color filter layer in a direction perpendicular to an upper surface of the substrate, the light transmission control layer having light transmittance that varies according to an electrical signal. The light transmission control layer overlaps the black matrix. A width of the light transmission control layer is greater than a width of the black matrix.
