  • Light emitting diode having side reflection layer
    Patent number: 11935990
    Abstract: A light emitting diode including a side reflection layer. The light emitting diode includes: a semiconductor stack and a light exit surface having a roughened surface through which light generated from an active layer is emitted; side surfaces defining the light exit surface; and a side reflection layer covering at least part of the side surfaces. The light exit surface is disposed over a first conductivity type semiconductor layer opposite to the ohmic reflection layer, all layers from the active layer to the light exit surface are formed of gallium nitride-based semiconductors, and a distance from the active layer to the light exit surface is 50 ?m or more.
