Abstract: In one aspect, a light emitting display device includes a plurality of subpixels on a substrate, each of the plurality of subpixels having a corresponding emission region, each of the plurality of subpixels having an outer interface with an n-gonal shape; a light emitting diode at each corresponding emission region and including an emission layer; and a plurality of arc-shaped light reflectors inside the light emitting diode and having a lower refractive index than a refractive index of the emission layer. The plurality of arc-shaped light reflectors are in a quasi-caustic region of the outer interface.

Abstract: Disclosed is a stereoscopic image display device which separates views from each other to reduce crosstalk and minimizes reduction in brightness due to decrease of an opening area of sub-pixels. The stereoscopic image display device includes a display panel including first and second sub-pixels arranged in parallel in the horizontal direction in each of regions formed by intersecting a plurality of gate lines and a plurality of data lines, openings for opening a part of each of the first and second sub-pixels in a light-shielding pattern configured to shield regions of the first and second sub-pixels other than the openings, and a parallax unit located on the display panel and including a plurality of lenses.

Abstract: A light emitting display device includes an inclined reflective portion that is below a bank and disposed in each of a plurality of pixel regions. The device includes a light emitting diode disposed in an opening. Each of the plurality of pixel regions is configured such that the corresponding opening and reflective portion have a cardioid-shaped structure with a cusp. A display region includes a first region of a first PPI and a second region of a second PPI smaller than the first PPI. The pixel region disposed in the first region has a first type cardioid-shaped structure, and the pixel region disposed in the second region has a second type cardioid-shaped structure. The first type cardioid-shaped structure has a smaller rate of change in curvature than the second type cardioid-shaped structure.
