1. A display device comprising:
a first sub-pixel area where a light of a first color is emitted;
a second sub-pixel area where a light of a second color is emitted;
a display part comprising an encapsulation layer and an emission layer configured to emit light, the emission layer comprising a first emission layer in the first sub-pixel area and a second emission layer in the second sub-pixel area; and
a sensor part disposed on the display part and comprising:
an insulating base layer disposed on the encapsulation layer and contacting an upper surface of the encapsulation layer,
a first conductive pattern layer including a first sensing electrode, the first conductive pattern layer disposed on the insulating base layer and contacting an upper surface of the insulating base layer,
a second conductive pattern layer including a second sensing electrode,
a protective layer disposed on the second conductive pattern layer and contacting an upper surface of the second conductive pattern layer,
and a functional insulating layer disposed between the first conductive pattern layer and the second conductive pattern layer,
wherein:
a single layer of the functional insulating layer is configured to absorb light in a first non-emission wavelength band and a second non-emission wavelength band different from a wavelength band of the light to be emitted from the emission layer,
the single layer of the functional insulating layer configured to absorb light in the first non-emission wavelength band and the second non-emission wavelength band contacts an upper surface of the first conductive pattern layer and a lower surface of the second conductive pattern layer, and
the functional insulating layer is disposed across the first sub-pixel area and the second sub-pixel area, and a first portion of the functional insulating layer in the first sub-pixel area and a second portion of the functional insulating layer in the second sub-pixel area include a same material.
