    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 light emitting display device includes a substrate including a display area and a non-display area adjacent to the display area; a lower pad electrode on the substrate in the non-display area; a planarization layer overlapping the lower electrode; an upper pad electrode on the lower pad electrode and overlapping at least a portion of the lower planarization layer. The planarization layer includes an opening exposing an upper surface of the lower pad electrode, the lower pad electrode and the upper pad electrode are electrically connected to each other through the opening, the lower planarization layer includes an exposed portion exposing an upper surface of the lower planarization layer, and an overlapping portion overlapping at least a portion of the upper pad electrode, and a height of the upper surface of the exposed portion is lower than a height of an upper surface of the overlapping portion.
