More Information
Summary:Provided is a display device that can retard the degradation of light-emitting elements even when the display device is used in a high temperature environment. A display device includes a TFT layer, a light-emitting element layer provided with a plurality of light-emitting elements, a heat dissipating layer, an extraction member, and a thermal insulation layer that insulates the light-emitting elements from external heat. The thermal insulation layer is made from a material containing a first resin in which a metal complex compound having an ammonium salt as a ligand is dispersed. The TFT layer is formed between the heat dissipating layer and the light-emitting element layer. The heat dissipating layer overlaps the light-emitting elements. The thermal insulation layer surrounds the heat dissipating layer. The extraction member is formed to overlap the thermal insulation layer. The heat dissipating layer and the thermal insulation layer are in direct contact with the TFT layer.
