LIQUID CRYSTAL DISPLAY UNIT

摘要

A reflection type or translucent type liquid crystal display unit comprising a liquid crystal cell, an optical anisotropic element and an output-side polarizer, the optical anisotropic element having a ratio Re(450)/Re(550) of up to 1.007 between an in-plane retardation value (Re(550)) measured at wavelength 550nm and an in-plane retardation value (Re(450)) measured at wavelength 450nm. An OCB mode liquid crystal display unit comprising a liquid crystal cell, a pair of output-side polarizers holding the liquid crystal cell between them and an input-side polarizer, and an optical compensation plate, wherein the optical compensation plate has an in-plane retardation Re, a thickness-direction average refractive index is smaller than an in-plane average refractive index, and a refractive index varies in a thickness direction. The output-side polarizers contain antireflection films respectively on the surfaces thereof away from the liquid crystal cell, and each antireflection film is a laminate containing a low-refractive-index layer containing aero-gel and having a refractive index of up to 1.37.
