Abstract: An organic light emitting diode (OLED) display includes a substrate, an organic light emitting diode, and a first barrier layer. The organic light emitting diode is disposed on the substrate, in which the projection of the organic light emitting diode on the substrate has a first profile. The first barrier layer is disposed on the organic light emitting diode, in which the projection of the first barrier layer on the substrate has a second profile. The first profile is non-conformal with the second profile.
