Abstract
An organic light emitting diode display includes a substrate, a thin film transistor on the substrate, a first electrode on and connected to the thin film transistor, a pixel defining layer on the first electrode and defining a pixel area, an organic light emitting layer on the first electrode and contacting the first electrode exposed in the pixel area, a second electrode on the organic light emitting layer, and a light blocking layer on the second electrode and exposing the second electrode at a position corresponding to the pixel area. The light blocking layer may include a first metal layer on the second electrode and exposing the second electrode at a position corresponding to the pixel area, a first intermediate layer covering the first metal layer, a second metal layer covering the first intermediate layer, and a second intermediate layer covering the second metal layer.
