Abstract: A light emitting display device includes: a display area; a first component area positioned within the display area and that includes a plurality of pixels, each pixel of the plurality of pixels respectively includes a pixel circuit part, and the first component area further includes a first photosensor area and a second photosensor area between the plurality of pixels. The first photosensor area includes: a first sub-photosensor area positioned between adjacent pixel circuit parts; and a light blocking layer positioned on a front surface of the first sub-photosensor area and that includes an opening that overlaps the first sub-photosensor area on a plane. The second photosensor area includes: a second sub-photosensor area positioned between the adjacent pixel circuit parts; and the light blocking layer positioned on a front surface of the second sub-photosensor area and that overlaps the second sub-photosensor area.

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.
