A light-emitting diode (LED) device configured to provide a multi-color display includes a plurality of light-emitting cells at least partially defined by a partition layer. The LED device may be configured to reduce optical interferences between the light-emitting cells. The LED device includes a plurality of light-emitting structures spaced apart from one another; a plurality of electrode layers on respective first surfaces of the light-emitting structures, a separation layer configured to electrically insulate the light-emitting structures from each other; phosphor layers on respective second surfaces of the light-emitting structures and associated with different colors, and a partition layer between the phosphor layers to separate the phosphor layers from one another. Each light-emitting cell may include a separate light-emitting structure, a separate set of one or more electrodes, and a separate phosphor layer.

A light-emitting diode (LED) device includes a plurality of light-emitting structures spaced apart from each other; a plurality of electrode layers on first surfaces of the plurality of light-emitting structures, respectively; a protection layer on second surfaces of each of the plurality of light-emitting structures, respectively; a separation layer to electrically insulate the plurality of light-emitting structures from each other and electrically insulate the plurality of electrode layers from each other; a plurality of phosphor layers on second surfaces of the plurality of light-emitting structures, respectively, each of the plurality of the phosphor layers each to output a different color of light; and a partitioning layer between the phosphor layers and separating the plurality of phosphor layers from each other, the partitioning layer including a substrate structure, an insulation structure, or a metal structure.

Light-emitting diode (LED) device for realizing multi-colors

A semiconductor light-emitting device includes a first conductive type semiconductor layer having a main surface, a plurality of vertical type light-emitting structures protruding upward from the first conductive type semiconductor layer; a transparent electrode layer covering the plurality of vertical type light-emitting structures; and an insulation-filling layer disposed on the transparent electrode layer. The insulation-filling layer extends parallel to the first conductive type semiconductor layer so as to cover the plurality of vertical type light-emitting structures. A selected one of the first conductive type semiconductor layer and the insulation-filling layer, which is disposed on a light transmission path through which light generated from the plurality of vertical type light-emitting structures is radiated externally, has an uneven outer surface. The uneven outer surface is opposite to an inner surface of the selected one, and the inner surface faces the plurality of vertical type light-emitting structures.
