Abstract

A display panel includes: first and second pixel circuits on a substrate; first and second pixel electrodes electrically connected to the first and second pixel circuits, respectively; a pixel defining layer having openings overlapping with the first and second pixel electrodes, respectively; a first emission layer on the first pixel electrode; a second emission layer on the second pixel electrode; an opposite electrode on the first emission layer and the second emission layer; and an anti-reflection layer on the opposite electrode. The anti-reflection layer includes: a light-blocking portion corresponding to an area between the openings of the pixel defining layer; a first color filter overlapping with the first emission layer; a second color filter overlapping with the second emission layer; and an overcoat layer including a portion located in a separation space between the light-blocking portion and at least one of the first color filter or the second color filter.
