Abstract
An organic light emitting display device including an emission unit and a pixel circuit unit. The emission unit includes an organic light emitting diode. The pixel circuit unit includes a driving transistor, at least one or more switching transistors, a capacitor, a light blocking unit, and an opening in which the light blocking layer is not formed. The light blocking unit includes a light blocking layer which blocks light input to the pixel circuit unit. The pixel circuit unit is configured to drive the emission unit and selectively block the light input to the pixel circuit unit.
