Abstract
A polycarbonate resin film of the present invention is formed from a polycarbonate resin which contains at least a constitutional unit derived from a dihydroxy compound having a bonded structure represented by the following structural formula (1) and satisfies the following expression (2) when subjected to a tensile test at a standard stretching temperature for the polycarbonate resin and at a pulling speed (strain rate) of 1,000%/min.[Chem. 1]CH—O  (1)(No hydrogen atom is bonded to the oxygen atom contained in the structural formula (1).)0.9≦[(lower yield stress in tension)/(upper yield stress in tension)]≦1  (2).
