Display device including support films

A display device comprising:

• a substrate having flexibility, and a first surface and a second surface opposing the first surface;
• a display part arranged with a plurality of pixels arranged;
• a frame part having a drive element for driving the plurality of pixels arranged around the display part;
• a mounting part including an individual circuit element mounted on the substrate and a connection element;
• a first adhesive layer arranged on the second surface of the substrate and arranged opposing the display part and the frame part;
• a first support film above the first adhesive layer;
• a second adhesive layer arranged above the second surface of the substrate and arranged opposing the mounting part;
• and
• a second support film above the second adhesive layer;
• a third support film located between the first support film and the second support film;
• and
• a fourth support film located between the first support film and the second support film,
• wherein
• the display part, the frame part, the mounting part, and a bent part are on the first surface of the substrate,
• the bent part is arranged between the frame part and the mounting part,
• the first adhesive layer and the first support film separated from the second adhesive layer and the second support film,
• the second support film has a higher thermal conductivity compared to the first support film,
• the third support film is connected to the first support film and the second support film,
• the fourth support film is connected to the first support film and the second support film, and
