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.
