ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE

Abstract:

An organic light emitting diode display device includes 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, wherein a surface of the plurality of microlenses in a sampling area of the emitting area is divided into a plurality of convex portions and a plurality of concave portions with respect to a central surface, and a total volume of the plurality of convex portions with respect to the central surface is equal to a total volume of the plurality of concave portions with respect to the central surface.
