Abstract
A polyimide film and a flexible display device cover substrate using the same are provided, and the polyimide film includes a polyimide and a blue infrared absorbing agent. The blue infrared absorbing agent includes cesium tungsten oxide, tungsten oxide, Prussian blue, or antimony tin oxide. The blue infrared absorbing agent has infrared absorbing and photothermal conversion effects, and the surface temperature of the polyimide resin may be increased by infrared irradiation, so as to shorten the baking time.
