Organic light emitting display with luminescent layers having varying thicknesses to improve color reproducibility

Abstract

An organic light emitting display is disclosed. In one aspect, the display includes a substrate, thin film transistors disposed on the substrate, first, second, and third pixel definition layers disposed on the thin film transistors, respectively having openings, and respectively having first, second, and third heights different from each other, and first, second, and third organic light emitting devices disposed in the openings of the first, second, and third pixel definition layers and connected to the thin film transistors, respectively. The first, second, and third pixel definition layers are spaced apart from each other, the first, second, and third organic light emitting devices have different thicknesses from each other, and the first, second, and third organic light emitting devices have thicknesses respectively corresponding to the first, second, and third heights of the first, second, and third pixel definition layers.

Dependencies are inferred from the claim text.
