| abstract | PROBLEM TO BE SOLVED: To provide a polyimide film for forming a display device in which warpage is suppressed and there is no anisotropy of thermal expansion coefficient in the longitudinal direction and the width direction. SOLUTION: It consists of a single layer or a plurality of polyimide layers, (a) the thickness is in the range of 3 μm to 50 μm, (b) the thermal expansion coefficient is 10 ppm / K or less, (c) 23 Keep the convex surface at the center of the polyimide film of 50 mm square after humidity conditioning for 20 hours at ℃ and humidity of 50%, and keep it in contact with the flat surface. The average warpage amount is 10 mm or less, and (d) the difference between the thermal expansion coefficient (CTE-MD) in the longitudinal (MD) direction and the thermal expansion coefficient (CTE-TD) in the width (TD) direction is A polyimide film for forming a display device that satisfies ± 3 ppm / K or less. [Selection figure] None |
