<p>Provided is a liquid crystal display device with excellent viewing angle properties, especially a twisted nematic (TN) type liquid crystal display device. The liquid crystal display device has at least: a first and a second polarizing layer arranged with the absorption axes being orthogonal to each other; a first and a second substrate arranged opposite to each other between the first and second polarizing layers, at least either one of which has a transparent electrode; a twisted alignment mode liquid crystal cell arranged between the first and second substrates; a first optical compensation film arranged between the first polarizing layer and the liquid crystal cell, including a composition containing a first transparent support body and a polymerizable liquid crystal compound; and a second optical compensation film arranged between the second polarizing layer and the liquid crystal cell, including a second transparent support body. The in-plane retardation Re1 (550) at a wavelength of 550 nm in the first optical compensation film satisfies the following formula (I). In the plane orthogonal to an in-plane retardation axis, the ratio of a retardation R [+40] measured at an angle of 40° inclined from the normal direction to a retardation R [-40] measured at an angle of 40° reversely inclined from the normal direction satisfies the following formula (II) or (II'). 10 nm <= Re1 (550) <= 200 nm (I) If R [+ 40] > R [- 40], 1. 1 <= R [+ 40] / R [- 40] <= 10 (II) If R [+ 40] < R [- 40], 1. 1 <= R [- 40] / R [+ 40] <= 10 (II') The absorption axis of the first polarizing plate is orthogonal to the rubbing direction of the liquid crystal cell substrate adjacent to the first polarizing plate, and the absorption axis of said first polarizing plate is orthogonal to the in-plane retardation axis of the first optical compensation film. Additionally, the in-plane retardation axis of the second optical compensation film is parallel to or orthogonal to the second absorption axis, and the in-plane retardation Re2 (550) at a wavelength of 550 nm of the second optical compensation film satisfies the following formula (III), and the retardation Rth2 (550) at a wavelength of 550 nm in the thickness direction of the second optical compensation film satisfies the following formula (IV). 0 nm <= Re2 (550) <= 150 nm (III) -20 nm <= Rth2 (550) <= 250 nm (IV)</p> |
