Display device, electronic device including the same, and method for manufacturing the display device

An electronic device, comprising:

• a display panel;
• and
• a heat dissipating member below the display panel,
• wherein the heat dissipating member comprises:
• a heat dissipating plate comprising graphite;
• an adhesive layer on at least one of a bottom surface or a top surface of the heat dissipating plate;
• and
• a base material film spaced apart from the heat dissipating plate with the adhesive layer therebetween,
• wherein the adhesive layer comprises a polyol comprising a polycarbonate polyol and a polyisocyanate that crosslinks with the polyol,
• wherein, when a total content of the polyol and the polyisocyanate is taken to be 100 parts by weight, a content of the polycarbonate polyol is about 20 parts by weight to about 40 parts by weight,
• wherein the adhesive layer comprises a first portion adjacent to the heat dissipating plate and a second portion adjacent to the base material film,
• wherein, in the adhesive layer, a content of the polycarbonate polyol of the first portion is less than a content of the polycarbonate polyol of the second portion.

A method for manufacturing a display device, the method comprising:

• providing a display panel;
• and
• forming a heat dissipating member below the display panel,
• wherein the forming of the heat dissipating member comprises:
• providing a heat dissipating plate comprising graphite;
• providing a base material film;
• providing an adhesive composition between the heat dissipating plate and the base material film to form a preliminary adhesive layer;
• and
• curing the preliminary adhesive layer to attach the heat dissipating plate and the base material film to each other,
• wherein the preliminary adhesive layer comprises a polyol comprising a polycarbonate polyol,
• wherein the preliminary adhesive layer comprises a first preliminary portion adjacent to the heat dissipating plate and a second preliminary portion adjacent to the base material film,
• wherein, in the preliminary adhesive layer, a content of the polycarbonate polyol of the first preliminary portion is less than a content of the polycarbonate polyol of the second preliminary portion.
