An optical member comprising a polymer which is amorphous and has a glass transition temperature of not lower than 110° C. and optical property parameters O'R(∞)) and O'G(∞) that satisfy the following inequality (1), |O'G(∞)|<-0.75x|O'R(∞)|+0.017 (1), is superior in its heat resistance and transparency and high in its stability of optical properties. Therefore, the optical member can be used as, for example, a constituent of optical systems in a liquid crystal display, thereby suppressing change in a display color tone depending on variation of using circumstances of the liquid crystal display.
