An organic light-emitting diode display device is disclosed. The organic light-emitting diode display device comprises a display panel where a plurality of pixels are arranged. The plurality of pixels comprise a first pixel having a first planar shape consisting of a plurality of points and a second pixel placed adjacent to the first pixel and having a second planar shape consisting of a plurality of points. The first planar shape contains a first point, which is the only point from which the shortest distance between the first pixel and the second pixel is obtained.
