Abstract: The present disclosure provides an electroluminescent display device comprising a lower substrate, an insulating layer and subpixels. The insulating layer is positioned on the lower substrate subpixels. The subpixels are positioned on the insulating layer and include light emitting diodes comprising at least two light emitting layers emitting different colors. The subpixels includes a first subpixel in which only one light emitting layer of the at least two light emitting layers emits light and a second subpixel in which both of two light emitting layers of the at least two light emitting layers emit light.

Abstract: A personal immersive device for virtual reality and/or augmented reality and a display thereof are disclosed. The personal immersive device comprises a plurality of subpixels arranged in a matrix on the substrate; a planarization film applied over an entire surface of a substrate; color filters and light-emitting elements disposed in the respective subpixels, over the planarization film; and an imaging lens that is smaller in size than the substrate and spaced a given distance apart from the substrate, wherein, in the first side area and second side area, the light-emitting elements are misaligned from the color filters.
