Abstract: A display device includes a substrate, and an array of pixels on the substrate, the array of the pixels including a first column in which first pixels emitting first color light and second pixels emitting second color light are alternately disposed in a first direction, and a second column adjacent to the first column. The second column includes third pixels that emit third color light and are disposed in the first direction. The second column includes groups each including two or more third pixels, and a first distance between adjacent third pixels included in a same group group is less than a second distance between adjacent third pixels included in different groups.

Abstract: A mask assembly may include a frame, first sticks, and masks. The first sticks may extend in a first direction and may be arranged in a second direction. The plurality of masks may be disposed on the frame and the first sticks. The plurality of masks may extend in the second direction and may be arranged in the first direction. Each of the first sticks may have a first edge and a second edge, which are opposite to each other in the second direction. When viewed in a plan view defined by the first and second directions, the first and second edges of an outermost stick of the first sticks may have different shapes, and linear lengths of the first and second edges of the outermost stick may be substantially equal to each other, where the linear lengths are lengths of the first and second edges in a straight state.

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.
