Zusammenfassung:	An object of the present invention is to provide a film which absorbs specific ultraviolet and does not have roll staining or bleed out according to a polycarbonate resin containing a specific polycarbonate resin and a specific ultraviolet absorber. The present invention relates to the polycarbonate resin film made of a polycarbonate resin composition which comprises 100 parts by weight of the polycarbonate resin containing a structural unit derived from a dihydroxy compound represented by the following formula (1); and more than 0.45 parts by weight and 7 parts by weight or less of the ultraviolet absorber having a melting point of 135 DEG C or higher and less than 300 DEG C and 5% weight loss temperature of higher than 240 DEG C relative to 100 parts by weight of polycarbonate resin, wherein light transmittance at a wavelength of 380nm is from 0.001% or more and 15% or less, and thickness is from 5[mu]m to 120[mu]m.
