Abstract: A display device includes: a pixel defining layer defining openings arranged in first and second directions, the openings forming emission areas in which light emitting elements are disposed to emit light of different colors; a light blocking layer disposed on the pixel defining layer, and defining holes, each overlapping the opening and having a larger diameter than the opening; and color filters disposed on the light blocking layer to overlap the holes and overlap the emission areas. The opening has an opening interval, which is defined as a difference in diameter between the overlapping hole and the opening, in the openings, among homogeneous openings in which the light emitting elements for emitting light of the same color are disposed, the homogeneous openings adjacent in the first or second direction have different opening intervals, and among the homogeneous openings, openings having different opening intervals are at least three types.

Abstract: A display device includes a pixel electrode, a wall layer, an emission layer, a touch electrode, and a light blocking member. The wall layer includes an opening exposing the pixel electrode. The emission layer overlaps the pixel electrode. The light blocking member overlaps the touch electrode and includes a first opening and a second opening each exposing the emission layer. A first perimeter section of the first opening is spaced from a first perimeter section of the opening by a first distance in a first direction in a plan view of the display device. A second perimeter section of the first opening is spaced from a second perimeter section of the opening by a second distance in a second direction in the plan view. The second distance is equal to the first distance. The second direction is at 45 degrees relative to the first direction.
