PROBLEM TO BE SOLVED: To provide a liquid crystal display device having high contrast, wherein satisfactory black display can be obtained. SOLUTION: The liquid crystal display device is provided with a liquid crystal cell 20 wherein liquid crystal molecules are twist-arranged when no voltage is applied and a lateral electric field is applied when voltage is applied, an optical compensation layer 30 superposed on the liquid crystal cell 20 and polarizing plates 10 and 40 disposed on the outer sides of the liquid crystal cell 20 and the optical compensation layer. When the liquid crystal cell 20 is observed in the normal direction of the liquid crystal cell 20, the direction of the lateral electric field is set to the intermediate direction between the axis directions of the liquid crystal molecules 13 close to respective interfaces of substrates 1 and 9 of the liquid crystal cell 20 and the directions of the transmission axes of the polarizing plates 10 and 40 are set to the directions nearly parallel or nearly orthogonal to the axis directions of liquid crystal molecule 13 and an optical compensation element 17 in the position closest to the polarizing plates 10 and 40, respectively, when no voltage is applied. |
