Abstract: A display device includes: a first substrate; a plurality of metal layers on the first substrate and separated from each other; a buffer layer on the metal layer; a semiconductor layer on the buffer layer; a gate conductive layer on the semiconductor layer; a data conductive layer connected to the semiconductor layer; and a light-emitting element connected to the data conductive layer, wherein the metal layer includes a first portion partially overlapping the semiconductor layer in a third direction perpendicular to the surface of the first substrate, a second portion where the metal layer completely overlaps the semiconductor layer in the third direction, and a third portion where the metal layer does not overlap the semiconductor layer in the third direction.
