Abstract
A novel liquid crystal display device (LCD) is disclosed. The LCD comprises at least, a member of generating polarized light, a retardation member, a first polarizing element, a liquid-crystal cell and a second polarizing element, in this order, wherein the retardation member satisfies at least one condition of
- (i) its in-plane retardation, Re, is from 10 nm to 3000 nm at a wavelength falling within a range from 400 to 780 nm, and
- (ii) its thickness-direction retardation, Rth, is from 60 nm to 3000 nm at a wavelength falling within a range from 400 to 780 nm.
