| 摘要 |
In the present invention, a phase-difference film contains a sugar ester, a retardation-elevating agent, and a cellulose ester resin that has acetyl groups and butyryl groups. The relationships 50 nm≤|Ro|≤80 nm and 200 nm≤|Rth|≤300 nm hold, where Ro (nm) is the in-plane retardation of the film, and Rth (nm) is the thickness-direction retardation of the film. |
