1. A display device comprising:
a light-emitting element layer provided with a plurality of light-emitting elements;
a thin-film transistor (TFT) layer provided below the light-emitting element layer and including one or more TFTs configured to drive the plurality of light-emitting elements;
at least one thermal insulation layer configured to thermally insulate the plurality of light-emitting elements from external heat, wherein the at least one thermal insulation layer comprises a molybdenum-containing complex and a polyphenylene sulfide-based resin;
a heat dissipating layer configured to dissipate heat from the plurality of light-emitting elements, wherein the TFT layer is formed between the heat dissipating layer and the light-emitting element layer; and
an extraction member connected to the heat dissipating layer and configured to extract the heat to outside of the display device, wherein in a plan view,
the heat dissipating layer overlaps the plurality of light-emitting elements,
the at least one thermal insulation layer surrounds a periphery of the heat dissipating layer, and
the extraction member is formed overlapping the at least one thermal insulation layer.
