Abstract
A display apparatus includes a circuit board including a driving circuit, and a pixel array including a plurality of pixels on the circuit board, each including a plurality of sub-pixels, and a light blocking partition between the plurality of sub-pixels. Each of the plurality of sub-pixels includes a lower light emitting diode (LED) cell configured to generate light of a first wavelength. A first sub-pixel includes a transparent resin structure on the first lower LED cell, a second sub-pixel includes an inter-cell insulating layer on the second lower LED cell and an upper LED cell having on the inter-cell insulating layer and configured to generate light of a second wavelength, and a third sub-pixel includes a wavelength conversion structure on the third lower LED cell and configured to convert light of the first wavelength into light of a third wavelength.
