1. A display device comprising:
a sensor layer comprising photo sensors;
a substrate positioned on the sensor layer;
a pixel layer positioned on the substrate and comprising pixels, wherein the substrate is positioned between the sensor layer and the pixel layer, and wherein the pixels comprise pixel electrodes;
a black matrix positioned on the pixel layer, comprising first-set openings respectively overlapping the pixel electrodes, and comprising second-set openings not overlapping any pixel electrodes of the display device in a direction perpendicular to the substrate, wherein the pixel layer is positioned between the substrate and the black matrix;
a color filter set positioned on the black matrix; and
a light blocking layer positioned between the substrate and the pixel layer and comprising through holes,
wherein at least one of the through holes overlaps the second-set openings,
wherein the color filter set includes at least one color filter overlapping one of the first-set openings and one of the second-set openings;
wherein the second-set openings entirely pass through the black matrix in the direction,
wherein the pixels comprise a first pixel and a second pixel each emitting first color light, a third pixel emitting second color light, and a fourth pixel emitting third color light,
wherein the first-set openings comprise a first first-set opening overlapping with the first pixel, a second first-set opening overlapping with the second pixel, a third first-set opening overlapping with the third pixel, and a fourth first-set opening overlapping with the fourth pixel, and
wherein at least two of the first first-set opening, the second first-set opening, the third first-set opening, and the fourth first-set opening are spaced from each other,
wherein the pixel layer comprises:
a circuit element layer comprising transistors that respectively overlap with the first-set openings and comprising an insulating layer that covers the transistors; and
a light emitting element layer positioned on the circuit element layer and comprising emitting layers that respectively overlap with the first-set openings, and
wherein the circuit element layer comprises light transmission holes that respectively overlap with the second-set openings.
