1. A display panel comprising:
a first pixel circuit and a second pixel circuit on a substrate, each of the first and second pixel circuits comprising a transistor, a storage capacitor, and a conductive line;
a first pixel electrode electrically coupled to the first pixel circuit;
a second pixel electrode adjacent to the first pixel electrode, and electrically coupled to the second pixel circuit;
a pixel defining layer covering edges of the first pixel electrode and edges of the second pixel electrode, and 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,
wherein the anti-reflection layer comprises:
a light-blocking portion corresponding to an area between the opening of the pixel defining layer overlapping with the first pixel electrode and the opening of the pixel defining layer overlapping with the second pixel electrode;
a first color filter overlapping with the first emission layer;
a second color filter overlapping with the second emission layer; and
an overcoat layer over the first and second color filters, the overcoat layer comprising a first portion filled in a separation space between the light-blocking portion and at least one of the first color filter or the second color filter in a plan view, the separation space overlapping with the pixel defining layer, and
wherein the light-blocking portion is located between the first color filter and the second color filter, and is spaced from the at least one of the first color filter or the second color filter to define the separation space between the light-blocking portion and the at least one of the first color filter or the second color filter in a plan view.
