The present invention provides a λ / 4 plate excellent in surface processing suitability and polarizer durability, and excellent in optical properties such as retardation and reverse wavelength dispersion, and a method for producing the same. In addition, a polarizing plate, a liquid crystal display device, and a stereoscopic image display device provided with the λ / 4 plate are provided. A λ / 4 plate containing a compound represented by a specific general formula and a cellulose ester resin, which is stretched in a direction oblique to the longitudinal direction, and has a temperature of 23 ° C. and a relative humidity of 55%. In RH, the in-plane retardation Ro (550) measured at a measurement wavelength of 550 nm is in the range of 100 to 160 nm, and the orientation angle θ is in the range of 40 to 50 °.
