OPTICAL FILM, PROCESS FOR PRODUCING OPTICAL FILM, POLARIZER COMPRISING THE SAME, LIQUID-CRYSTAL DISPLAY, AND COMPOUND

摘要

An optical film is provided which has a satisfactory haze, is reduced in bleeding even in long-term storage, and is free from film web deformation failures such as a ridge failure and protrusion failure. Also provided are: a process for producing an optical film; a polarizer comprising the film; a liquid-crystal display employing the polarizer; and a compound usable for forming the optical film. The optical film is characterized by comprising at least one compound represented by the following general formula (1) and a cellulose ester. (In the formula, R1 and R2 each independently represents a substituent; R3 represents hydrogen or alkyl; and n is an integer of 0-4; provided that the R1's may be the same or different.)
