Provided is a liquid crystal panel which is capable of significantly reducing a thickness thereof as compared to conventional liquid crystal panels, and, when used in a liquid crystal display device using a liquid crystal cell such as an IPS-type liquid crystal cell, reducing oblique light leakage in a black state of the liquid crystal display device to enhance contrast. Each of a pair of polarizers on respective opposite sides of a liquid crystal cell has a thickness of 10 µm or less, and exhibits optical properties including a single transmittance of 40.0% or more and a polarization degree of 99.8% or more. A retardation layer laminated to one of the opposite sides of the liquid crystal cell has a thickness of 25 µm or less, with a moisture permeability of 200 g/m 2 or less, wherein a value of ”nxy1 and a value of ”nxz1 are, respectively, 0.0036 or more, and 0.0041 or more, and Re and Rth are, respectively, in the range of 90 nm to 140 nm and the range of 100 nm to 240 nm, where ”nxy1 represents a difference between a refractive index nx1 in a slow axis direction and a refractive index ny1 in a fast axis direction; ”nxz1 represents a difference between the refractive index nx1 in the slow axis direction and a refractive index nz1 in a thickness-wise direction, Re represents an in-plane retardation, and Rth represents a thicknesswise retardation expressed in the formula Rth = (nx1-nz1) × d1, where d1 represents a thickness of the first retardation layer. |
