1. A display device comprising:
a plurality of pixels comprising a plurality of emission areas in which light emitting elements for emitting light are disposed and arranged in a first direction and a second direction crossing the first direction;
a light blocking layer disposed between the emission areas adjacent to each other, and defining a plurality of holes, wherein each of the holes overlaps a corresponding emission area of the emission areas and has a different diameter from the corresponding emission area; and
a plurality of color filters disposed in the holes of the light blocking layer and overlapping the emission areas,
wherein the emission areas comprise a plurality of first emission areas for emitting light of a first color, a plurality of second emission areas for emitting light of a second color having a shorter wavelength band than the light of the first color, a plurality of third emission areas for emitting light of a third color having a wavelength band between the light of the first color and the light of the second color, and a plurality of fourth emission areas for emitting light of the third color,
the plurality of holes comprises first holes overlapping the first emission areas, second holes overlapping the second emission areas, third holes overlapping the third emission areas, and fourth holes overlapping the fourth emission areas,
in one of the pixels in a plan view, a first opening interval between a corresponding first emission area of the first emission areas and a corresponding first hole of the first holes, a second opening interval between a corresponding second emission area of the second emission areas and a corresponding second hole of the second holes, and a third opening interval between a corresponding third emission area of the third emission areas and a corresponding third hole of the third holes are different from each other, and
a corresponding fourth emission area of the fourth emission areas is differently sized from the corresponding third emission area of the third emission areas and a corresponding fourth hole of the fourth holes is differently sized from the corresponding third hole of the third holes such that a fourth opening interval between the corresponding fourth emission area and the corresponding fourth hole is different from the third opening interval.
