## Abstract

An arcuate display device includes a plurality of display units each having has a plurality of pixels, a virtual axis, and a plurality of driving devices. Each pixel includes first, second, and third light-emitting elements respectively disposed at first, second, and third positions. The driving devices corresponding to the display units having the same minimum distance from the virtual axis have the same circuit layout design. The first, second, and third positions are sequentially arranged in a direction away from the virtual axis. Optical properties of the first light-emitting elements and the third light-emitting elements in at least a part of the pixels disposed at a first side of the virtual axis are respectively substantially the same as optical properties of the third light-emitting elements and the first light-emitting elements in at least a part of the pixels disposed at a second side of the virtual axis.
