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.
