ABSTRACT:
A liquid crystal element which comprises an oriented liquid crystal polymer and with which a liquid crystal display less apt to have display unevenness in a wide viewing range including the front and slant directions can be fabricated; and an optical element and a polarizing element each containing the liquid crystal element. The liquid crystal element comprises either a layer of an oriented liquid crystal polymer or a substrate and formed thereon the layer of an oriented liquid crystal polymer, wherein the liquid crystal polymer layer has an average in-plane haze of 10% or higher and a dispersion of the in-plane haze H (%) within the range represented by the relationship a-.sqroot.(10a).ltoreq.H.ltoreq.a+.sqroot.(10a) wherein "a" is the average haze (%), or has an average in-plane haze lower than 10% and a dispersion of the in-plane haze H (%) within the range represented by the relationship 0.ltoreq.H.ltoreq.b+.sqroot.(10b) wherein "b" is the average haze (%). The optical element comprises a multilayer structure comprising the liquid crystal element and a retardation film laminated thereon. The polarizing element comprises a multilayer structure comprising the liquid crystal or optical element and a polarizing plate laminated thereon.
