Abstract: An OLED display panel is provided which can dissipate heat generated from a circuit on the OLED display panel to the exterior using a structure which can rapidly reduce costs. A metal film 2 and insulation film 3 are formed between a glass substrate 1 and TFT drive circuit layer 4 in sequence from the side of the glass substrate 1. The metal film 2 conducts with a heat dissipation pattern 5b formed above the TFT drive circuit layer 4 from the metal film via a contact 15 which passes through the insulation film 3 and TFT drive circuit layer 4. The heat dissipation pattern 5b is connected to a metal frame 20 via a heat dissipation tape 21.
