ABSTRACT:
A liquid crystal display device includes an electrode substrate, a liquid crystal layer with no twist, a first retardation plate, a second retardation plate, polarizing plates, and a color filter. The first and second retardation plates have slow axes that are parallel or perpendicular to the alignment direction of liquid crystal molecules. The product of the refractive anisotropy Δn of the liquid crystal layer and the thickness d of the liquid crystal layer, the retardation R1of the first retardation plate and the retardation R2of the second retardation plate satisfy at least one of the relational expressions:in-line-formulae description="In-line Formulae" end="lead"?530 nm≦Δnd+R1+R2≦570 nm,in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?−20 nm≦Δnd−R1−R2≦20 nm,in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?255 nm≦Δnd−R1+R2≦295 nm, andin-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?255 nm≦Δnd+R1−R2≦295 nm.in-line-formulae description="In-line Formulae" end="tail"?
