POLYIMIDE FILM AND METHOD FOR MANUFACTURING SAME, FLEXIBLE PRINTED WIRING BOARD, SUBSTRATE FOR FLEXIBLE DISPLAY, FRONT PLATE FOR FLEXIBLE DISPLAY, LED ILLUMINATION DEVICE, AND ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE |
摘要 |
The present invention addresses the problem of providing: a polyimide film and a method for manufacturing the same, the polyimide film being suitable in a flexible printed wiring board or the like for an LED illumination device and having enhanced optical transparency, coloration resistance, and low-temperature bending resistance; a flexible printed wiring board which uses the polyimide film; a substrate for a flexible display; a front plate for a flexible display; an LED illumination device; and an organic electroluminescence display device. This polyimide film has a polyamic acid or polyimide formed by an acid anhydride or a derivative thereof, and a diamine or a derivative thereof, either one of which has a fluorene skeleton, the polyimide film being characterized in that the extension rate S of the film two minutes immediately after the film is humidified for 12 hours at 23°C and 55% RH and then immersed in pure water at 23°C is in a range of 0.01-0.10%/minute. |
