Abstract

An optoelectronic light emitting device includes a pixel with a transparent or translucent carrier substrate, on which a semiconductor light emitting arrangement with at least one micro LED is arranged. The micro LED extends over a partial area of the pixel. The main radiation direction of the semiconductor light emitting arrangement is directed onto a backscattering surface element arranged behind the transparent carrier substrate in viewing direction. The semiconductor light emitting arrangement includes a beam shaping element.
