Abstract

Embodiments of the present disclosure provide a display device comprising: a substrate; a thin film transistor layer on a first surface of the substrate and including a first hole; a light emitting element layer on the thin film transistor layer and including a light emitting element; a first light blocking layer between the substrate and the thin film transistor layer and including a second hole overlapping the first hole in a thickness direction of the substrate; and a second light blocking layer between the thin film transistor layer and the light emitting element layer and including a third hole overlapping the first hole and the second hole in the thickness direction of the substrate.
