Abstract:
A light emitting diode (LED) pixel for a display including a first LED stack, a second LED stack disposed on a partial region of the first LED stack, a third LED stack disposed on a partial region of the second LED stack, a first ohmic electrode disposed on the first LED stack and forming ohmic contact with the first LED stack, a second transparent electrode disposed between the second LED stack and the third LED stack and in ohmic contact with an upper surface of the second LED stack, and a third transparent electrode in ohmic contact with an upper surface of the third LED stack, in which the first ohmic electrode is laterally spaced apart from the second LED stack.
