    Abstract: A light emitting display device includes: a display panel includes: a display area and a component area surrounded by the display area and including a plurality of optical sensor areas, and an optical element located on a rear surface of the component area. The display area includes: a pixel defining layer defining an opening that overlaps an anode, a cathode covering the pixel defining layer, an encapsulation layer located on a top of the cathode, a color filter positioned on the encapsulation layer and overlapping the opening of the pixel defining layer. The color filter and the pixel defining layer each have an additional opening corresponding to the optical sensor area, and the additional opening of the color filter is narrower than the additional opening of the pixel defining layer, so that the pixel defining layer is obscured by the color filter in the optical sensor area.

    Abstract: An optical film includes a first pattern layer including a base part and protrusion part groups on the base part and having a first refractive index, and a second pattern layer on the first pattern layer and having a second refractive index greater than the first refractive index. Each of the protrusion part groups includes first and second protrusion parts adjacent to each other. Each of the first and second protrusion parts includes a bottom surface, an upper surface, a first side surface and a second side surface. The first and second protrusion parts are symmetrical with respect to a reference line passing through a center of each of the protrusion part groups and perpendicular to the base part. The first and second protrusion parts are asymmetrical with respect to a center line passing through a center of the upper surface and perpendicular to the bottom surface.
