1. A display device comprising:
a first substrate including at least one first opening part;
a pixel disposed on the first substrate;
at least one first heat dissipation layer disposed in the at least one first opening part;
an insulation layer disposed under the first substrate and including at least one second opening part overlapping the at least one first opening part; and
a second heat dissipation layer disposed in the at least one second opening part, wherein
the first and second heat dissipation layers are electrically disconnected to the pixel, and
in the at least one second opening part, the second heat dissipation layer is recessed toward the first heat dissipation layer to define a groove corresponding to the at least one second opening part.
