Abstract

An organic light emitting diode display device can include a substrate including at least one subpixel having a non-emitting area and an emitting area, a thin film transistor in the non-emitting area on the substrate, an overcoating layer on the thin film transistor and having a plurality of microlenses at a top surface of the overcoating layer, and a light emitting diode in the emitting area on the overcoating layer and connected to the thin film transistor. The surface of the plurality of microlenses can be divided into a plurality of convex portions and a plurality of concave portions with respect to a central surface. Further, the adjacent edge portions of adjacent two of the plurality of microlenses can constitute a first high portion, and the adjacent edge portions of adjacent three of the plurality of microlenses constitute a second high portion.
