Abstract: A display device includes a display panel including an antireflection layer on a light emitting element layer which includes a first pixel defining layer in which an opening defining a light emitting area of a first pixel is defined, and a second pixel defining layer in which an opening defining a light emitting area of a second pixel is defined. The antireflection layer includes first and second light blocking layers respectively overlapping the first and second pixel defining layers, and includes a first gap defined by a length of a predetermined direction from an edge of the opening to an edge of an opening of the first light blocking layer, and a second gap defined by a length from an edge of the opening to an edge of an opening of the second light blocking layer in the predetermined direction. The first gap is less than the second gap.
