PURPOSE: To prepare an oriented film which is capable of providing a liquid crystal display with excellent liquid crystal orientation, high contrast and high transmissivity in a bright state and further enables the manufacture of a very stable liquid crystal switching/display device by using a modified poly(hydroxystyrene) as a constituent material of the orient film for the liquid crystal display.

CONSTITUTION: This oriented film for a liquid crystal display contains: (a) a poly(hydroxystyrene) produced from a monomer represented by the formula (in the formula: R1 is H, CH3, F or Cl; and each of R2 and R3 is H, R4, OR4, SR4, OH, F, Cl, Br, NO2, a phenyl group or CH2X, independently from the other, wherein R4 is a 1-6C straight chain or branched chain alkyl group whose at least one hydrogen atom is optionally substituted by a fluorine atom and X is p-tosylate, 2-mesitylate, mesylate or triflate group, or OOC-CH3, OH, Cl or Br); and (b) at least one compound selected from among macrocyclic compounds, cryptands, coronands, podands, mercapto compounds and ionophores.
