Abstract
Disclosed is a unit pixel of a micro-display capable of minimizing light emitted through a side surface. A side surface of the unit pixel having a vertically stacked pixel structure is etched and has inclination angle. Light directed toward the side surface is reflected by the side surface inclined at an angle, and the light is emitted in a direction perpendicular to the growth surface or the surface of the growth substrate.
