1. A display device comprising:
a display panel comprising a base substrate, a thin-film transistor layer including thin-film transistors on the base substrate, and a light emitting element layer comprising light emitting elements on the thin-film transistor layer, wherein the base substrate comprises a light blocking layer between a first base and a second base;
a cover window on the light emitting element layer;
a fingerprint recognition sensor layer under the second base;
a protective member located between the second base and the fingerprint recognition sensor layer;
a first bonding layer located between the second base and the protective member; and
a second bonding layer located between the protective member and the fingerprint recognition sensor layer, and
wherein the light blocking layer comprises holes through which light reflected by a finger touching the cover window passes,
wherein the thin-film transistor layer is disposed on the first base,
wherein the protective member is bonded to the display panel by the first bonding layer, and the fingerprint recognition sensor layer is bonded to the protective member by the second bonding layer, and
wherein a material of the first base is the same as a material of the second base, and the first base and the second base each comprise a polymer material.
