The light-emitting unit has a microcavity structure and intensifies light with a specific wavelength. In the light-emitting units emitting light of different colors, reflective layers with different thicknesses are formed, an insulating layer is formed to cover the reflective layers, and then a top surface of the insulating layer is subjected to planarization treatment, whereby an insulating layer with different thicknesses is formed. After that, light-emitting elements emitting white light are formed over the planarized top surface of the insulating layer to overlap with the respective reflective layers, whereby the light-emitting units that intensify different colors due to different optical path lengths are separately formed.
