Abstract: The present disclosure relates to a light emitting display in which the light extracting efficiency is improved by using nano patterns (or nano particles). A light emitting display includes a substrate including a first pixel and a second pixel. The light emitting display includes a buffer layer on the substrate. The light emitting display includes a nano layer on the buffer layer. The light emitting display includes an anode electrode on the nano layer. The light emitting display includes a reflective layer between the buffer layer and the anode electrode.
