POLYIMIDE FILM, ORGANIC ELECTROLUMINESCENT ELEMENT, TRANSPARENT CONDUCTIVE LAMINATE, TOUCH PANEL, SOLAR CELL, AND DISPLAY DEVICE

摘要

A polyimide film comprising a polyimide that includes a repeating unit (A) represented by a specific general formula and a repeating unit (B) represented by a specific general formula, the proportion of the repeating unit (A) included relative to the total amount of the repeating units (A) and (B) being 10–70 mol%. The polyimide film has a linear expansion coefficient of no higher than 55 ppm/K, a tensile strength of at least 125 MPa, and a breaking elongation of at least 15%.
