    摘要： A compensator for an active matrix type liquid crystal display using a thin film transistor is provided. The compensator is made by a film of a liquid crystalline polymer which exhibits a twisted nematic orientation in a liquid crystal state and assumes a glassy state at temperatures below a liquid crystal transition point thereof, the constituent molecules of the liquid crystalline polymer film having a helical structure with a helical axis wherein the twist angle is in the range of 70 to 150 degrees, and the product Δ n · d of birefringence Δ n of the liquid crystalline polymer film and film thickness,d, being in the range of 0.2 to 3.0 µm.
