1. A display device comprising:
a substrate including:
a display area including emission areas and a light blocking area; and
a non-display area adjacent to the display area;
a thin-film transistor layer disposed on the substrate, the thin-film transistor layer comprising thin-film transistors;
a light-emitting element layer disposed on the thin-film transistor layer, the light-emitting element layer comprising light-emitting elements;
a wavelength conversion layer disposed on the light-emitting element layer that converts a peak wavelength of a light from at least a part of the light-emitting elements; and
a color filter layer disposed on the wavelength conversion layer, the color filter layer comprising:
color filters corresponding to the emission areas; and
a first light blocking part corresponding to the light blocking area and the non-display area,
wherein a transmittance of the first light blocking part with respect to a light having a wavelength of about 1000 nm or more is about 80% or more.
