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'<SUB>R</SUB>(∞)) and O'<SUB>G</SUB>(∞) that satisfy the following inequality (1), <?in-line-formulae description="In-line Formulae" end="lead"?>|O'<SUB>G</SUB>(∞)|<- 0.75x| O'<SUB>R</SUB>(∞)|+ 0.017 (1), <?in-line-formulae description="In-line Formulae" end="tail"?> 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.
