PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of displaying the picture of high quality by further dissolving phase differences corresponding to visual angles to be caused in a liquid crystal element and improving the lowering of the contrast ratio in the direction opposite to a visual angle, a coloring phenomenon and inversion phenomena in the left and right directions. SOLUTION: This liquid crystal display device 1 is constituted so that at least one sheet of phase difference plates 5a, 5b whose refractive index anisotropies are negative (na=nc>nb) and whose directions of main refractive indexes nb are inclined with respect to normals of surfaces and whose main refractive indexes nb are inclined in the clokwise direction or the counterclockwise direction around directions of main refractive indexes na or nc in the surfaces is interposed between a liquid crystal display element 4 to be constituted by sealing liquid crystal in between one pair of glass substrates 2, 3 and one pair of polarizers 6, 7 to be arranged on both sides of the liquid crystal display device 4. In this case, the retardation of the liquid crystal layer is set in a range which is larger than 300nm and is smaller than 550nm. |
