Abstract
A light emitting diode pixel for a display including a first LED sub-unit, a second LED sub-unit disposed on a first portion of the first LED sub-unit, and a third LED sub-unit disposed on a second portion of the second LED sub-unit, in which each of the first, second, and third LED sub-units includes a first conductivity type semiconductor layer and a second conductivity type semiconductor layer, light generated from the first LED sub-unit is configured to be emitted outside of the light emitting diode pixel through a third portion of the first LED sub-unit different from the first portion, and light generated from the second LED sub-unit is configured to be emitted outside of the light emitting diode pixel through a fourth portion of the second LED sub-unit different from the second portion.
