Claim:
A liquid crystal display device, comprising: a first substrate including a first polarizing layer on a light-input side; a second substrate including a second polarizing layer on another side, the first polarizing layer and the second polarizing layer having absorption axes substantially perpendicular to each other; a liquid crystal layer in which a liquid crystal molecule is aligned so as to be substantially horizontal to the first substrate and the second substrate; a matrix-drive electrode group having a pair of electrodes provided in each pixel on a side closer to the liquid crystal layer one of the first substrate and the second substrate; a rear-surface illuminating device; at least one optical compensating member; and a color filter layer provided between the first substrate and the second substrate, wherein: in a case where an absorption axis of the first polarizing layer and an optical axis of the liquid crystal layer are substantially perpendicular to each other, the at least one optical compensating member is provided between the first polarizing layer and the liquid crystal layer, and a refractive index between the second polarizing layer and the liquid crystal layer is substantially isotropic; in a case where the absorption axis of the first polarizing layer and the optical axis of the liquid crystal layer are substantially parallel to each other, the at least one optical compensating member is provided between the second polarizing layer and the liquid crystal layer, and a refractive index between the first polarizing layer and the liquid crystal layer is substantially isotropic; the absorption axis of the first polarizing layer and a slow axis of the at least one optical compensating member are substantially perpendicular to each other; the color filter layer satisfies nx≈ny≠nz for each of red (R) pixels, green (G) pixels, and blue (B) pixels; at least one of thickness-direction retardations Rth(R), Rth(G), and Rth(B) for the red (R) pixels, the green (G) pixels, and the blue (B) pixels is different from the thickness-direction retardations for the other pixels; and Rth(R) for the red (R) pixels satisfies Rth(R)>0 nm.
