Abstract
A display apparatus and a micro-light emitting diode are disclosed. The display apparatus includes: a first substrate including a light emitting diode part including a plurality of light emitting diodes regularly arranged on the first substrate. The display apparatus is implemented using micro-light emitting diodes formed of nitride semiconductors and thus can provide high efficiency and high resolution to be applicable to a wearable apparatus while reducing power consumption. The micro-light emitting diodes may include a wall element so as to be applied to a display substrate by force.
