Abstract: An organic light-emitting display panel includes a first display region including a plurality of first sub-pixels and a second display region including a plurality of second sub-pixels. Each of the sub-pixels includes a pixel circuit having a driving transistor to output driving current to an output node based on a data signal, a storage capacitor to store a voltage difference between the driving voltage and the gate voltage of the driving transistor, a switching transistor to transfer the data signal to the driving transistor, and a light-emitter connected to emit light based on the driving current. An overlap area of the gate electrode of the driving transistor and an anode electrode of the light-emitter in the first sub-pixel is smaller than an overlap area of the gate electrode of the driving transistor and an anode electrode of the light-emitter in the second sub-pixel.
