1. An organic light emitting diode display device comprising:
a substrate including a display region and a module region, wherein the display region includes a first pixel region, and the module region includes a second pixel region and a transmissive region;
a first pixel structure disposed in the first pixel region on the substrate;
a second pixel structure disposed in the second pixel region on the substrate;
a thin film encapsulation structure disposed on the first and second pixel structures, wherein a light transmittance of a portion of the thin film encapsulation structure in the display region is different from a light transmittance of a portion of the thin film encapsulation structure in the module region, and the portion of the thin film encapsulation structure in the module region includes a plurality of scatterers; and
a functional module disposed in the module region on a bottom surface of the substrate.
