Abstract

A light emitting diode display apparatus includes a display substrate having a plurality of subpixel areas; and a light emitting diode disposed on the display substrate to correspond to a corresponding subpixel area of the plurality of subpixel areas, wherein the light emitting diode includes an emission area and a non-emission area adjacent to the emission area, wherein the light emitting diode includes a trench part provided to overlap a boundary between the emission area and the non-emission area, and wherein the trench part is configured such that a side light emitted from the emission area is reflected in a display direction of the light emitting diode display apparatus.
