Abstract:
1. A liquid crystal display device comprising: a first substrate with a first polarizing layer at an incident side of light; a second substrate with a second polarizing layer which includes an absorption axis such that the smaller of two angles formed with respect to the absorption axis of the first polarizing layer ranges from 88° to 90°; a liquid-crystal layer on which liquid-crystal molecules are oriented such that the smaller of two angles formed with respect to the first substrate or the second substrate ranges from 0° to 5°, and such that the smaller of two angles formed with respect to the absorption axis of the first polarizing layer ranges from 88° to 90° or the smaller of two angles formed ranges from 0° to 2°; a matrix-driven electrode group with one pair of electrodes arranged on a pixel-by-pixel basis at a side close to the liquid-crystal layer, on either the first substrate or the second substrate; and a rear-illuminating device; wherein: between the first polarizing layer and the liquid-crystal layer, a first optical compensating member is disposed without a birefringent medium sandwiched between the liquid-crystal layer and the first optical compensating member; the first optical compensating member is constructed so that when a refractive index thereof in a slow-axis direction in a plane parallel to the substrate is taken as n1, a refractive index in a fast-axis direction in the plane parallel to the substrate is taken as n2, and a refractive index in a thickness direction is taken as n3, the first optical compensating member satisfies n1≈n3>n2; a slow axis of the first optical compensating member in the plane parallel to the substrate is substantially vertical to an optical axis of the liquid-crystal layer; color filters for an N number of colors (N≧2) are provided on the first substrate or the second substrate; and when wavelengths that denote maximum transmittance values of the color filters are each expressed as λ is satisfied for all M's (M=1, 2, etc., up to N).
