In a liquid crystal display 90 , a laminated retardation optical element 10 is placed between a polarizer 102 A on the incident side and a liquid crystal cell 104 , and a ~/4 retardation film 102 C 10 is placed between a polarizer 102 B on the emergent side and the liquid crystal cell 104 . The laminated retardation optical element 10 comprises: a ~/4 retardation layer 14 having the function of bringing, to light that passes through this retardation layer, a 15 phase difference corresponding to a quarter of the wavelength of the light; and a C plate-type retardation layer 16 that acts as a negative C plate. The ~/4 retardation layer 14 and the C plate-type retardation layer 16 are laminated to a transparent substrate 12 in 20 the order mentioned, and are optically bonded to each other. The I/4 retardation layer 14 comprises as its main component a horizontally-aligned, cross-linked nematic liquid crystal, while the C plate-type retardation layer 16 comprises as its main component a 25 cross-linked chiral nematic liquid crystal (a cross-linked nematic liquid crystal and a cross-linked chiral agent) or cross-linked discotic liquid crystal.
