1. A display device comprising:
a substrate; and
an array of pixels on the substrate, the array of the pixels defined by a pixel defining layer and comprising:
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;
a second column adjacent to the first column, the second column comprising third pixels that emit third color light and are disposed in the first direction; and
a first light-emitting diode, a second light-emitting diode, and a third light-emitting diode respectively corresponding to a first pixel of the first pixels a second pixel of the second pixels, and a third pixel of the third pixels, wherein
the second column includes groups each including two or more third pixels,
a first distance between adjacent third pixels included in a same group is less than a second distance between adjacent third pixels included in different groups,
the pixel defining layer includes:
a first portion extending between the adjacent third pixels included in the same group, and
a second portion extending between the adjacent third pixels included in the different groups,
each of the first light-emitting diode, the second light-emitting diode, and the third light emitting diode comprises a pixel electrode, and
an emission layer which overlaps a pixel electrode of the third light emitting diode overlaps another third electrode of another third light-emitting diode corresponding another third pixel in the same group.
