A novel optical compensatory sheet is disclosed the sheet comprises a transparent support and an optically anisotropic layer formed of discotic liquid-crystal molecules thereon. The anisotropic layer comprises at least one air interface control agent, thereby having an air interface polarity of at least 1.5-fold relative to that of a layer which does not comprise said air interface control agent. An optical compensatory sheet comprising a transparent support and an optically anisotropic layer formed of discotic liquid-crystal molecules thereon, wherein said anisotropic layer comprises at least one compound denoted by formula (I) is also disclosed
