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.

Abstract: A display device includes: a substrate including first and second sides; first and second pixels connected to different scan lines; a light blocking layer defining first and second light emission areas of the first and second pixels; and patterns overlapping the first and second light emission areas and on different layers between a pixel electrode and the substrate. Each emission area is divided into first and second divided areas, between which the first divided area is the closer to the first side. In the first light emission area, an overlap area between the second divided area and the first pattern is larger than an overlap area between the first divided area and the first pattern. In the second light emission area, an overlap area between the first divided area and the first pattern is larger than an overlap area between the second divided area and the first pattern.
