Abstract
A unit pixel of a Red-Green-Cyan-Blue (RGCB) microdisplay is disclosed. In the unit pixel, sub-pixels that form blue light, green light, cyan light, and red light, are vertically stacked on a growth substrate. Accordingly, the unit pixel area may be reduced, and pixel transfer processing is facilitated.
