Abstract: 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.
