Abstract: A light emitting diode includes a pixel unit. The pixel unit may include a first sub-pixel configured to emit white light. The first sub-pixel may include a first microcavity adjustment layer, a scattering layer, a first transparent electrode layer, a first emitting layer, and a first semi-transparent electrode layer. The scattering layer includes a plurality of patterns formed on a surface of the scattering layer. The scattering layer may be configured to reduce color cast of the first sub-pixel to be less than about 0.025 at viewing angles in a range of about −50 degree to +50 degree.
