/Display Device Using Micro-led Element
Abstract

A display apparatus includes a plurality of pixel areas being defined by crossing a data line and a gate line on substrate. The plurality of pixel areas includes a pixel circuit part and a display element layer. The display element layer includes a first electrode layer connecting to the pixel circuit part electrically, a second electrode layer being spaced from the first electrode layer electrically, and a micro-LED element being coupled to the first electrode layer and the second electrode layer. The micro-LED element includes an n-type semiconductor layer, an active layer being disposed on the n-type semiconductor layer, a p-type semiconductor layer being disposed on the active layer, an insulation layer surrounding an outer perimeter surface of the active layer at least, and a multilayer electrode part being disposed on an outer perimeter surface of the insulation layer.
