An object of the present invention is to provide a resin film which suppresses defects such as scratches caused by fluttering of a film in a manufacturing process and has optical properties required for a front plate, and a method for manufacturing the same. The present invention is a resin film comprising at least one of a polyimide resin or a polyamide resin, the length of the center point of the film width direction as the TD c, to the end portion from the center point in the width direction in, when the center point of the 80% length point of was TD 80 0%, the in-plane retardation value of TD c measured at a wavelength 590 nm R (TD c) and TD 80 plane retardation value R of the (TD 80 ) provides a resin film satisfying the formula (1). R (TD c) / R ( TD 80) ≧ 0.35 (1) [Selection diagram] Fig. 1 |
