PROBLEM TO BE SOLVED: To provide an OLED display panel capable of radiating heat generated from a circuit on an OLED display panel to the outside through a structure capable of reducing cost as low as possible.SOLUTION: A metal film 2 and an insulating film 3 are formed between a glass substrate 1 and a TFT drive circuit layer 4, in the order, from a side of the glass substrate 1. The metal film 2 is electrically continuous to a heat dissipation pattern 5b formed of a metal film on the TFT drive circuit layer 4, through a contact 15 penetrating through the insulating film 3 and the TFT drive circuit layer 4. The heat dissipation pattern 5b is connected to a frame 20 made of metal via a heat dissipation tape 21. |
