| titleOfInvention | Liquid crystal display device |
| abstract | The present invention provides a liquid crystal display device that can be easily produced and has a high contrast ratio in a wide viewing angle range. The liquid crystal display device of the present invention includes in the following order: a first polarizer; a first birefringent layer (II) (nx<ny≦nz); a first quarter-wave plate (nx>ny≧nz); a liquid crystal cell; a second quarter-wave plate having an Nz coefficient substantially equal to that of the first quarter-wave plate; a second birefringent layer (II) having an Nz coefficient and an in-plane retardation that are substantially equal to an Nz coefficient and an in-plane retardation of the first birefringent layer (II), respectively; and a second polarizer, wherein the device includes at least one birefringent layer (III) (nx≈ny≧nz) disposed at least one of: between the first birefringent layer (I) and the liquid crystal cell; and between the liquid crystal cell and the second birefringent layer (I); the first quarter-wave plate has an in-plane slow axis forming an angle of about 45° with an absorption axis of the first polarizer; the second quarter-wave plate has an in-plane slow axis substantially orthogonal to the in-plane slow axis of the first quarter-wave plate; the second polarizer has an absorption axis substantially orthogonal to the absorption axis of the first polarizer; the first birefringent layer (II) has an in-plane fast axis substantially orthogonal to the absorption axis of the first polarizer; the second birefringent layer (II) has an in-plane fast axis substantially orthogonal to the absorption axis of the second polarizer; and the device displays a black screen by aligning liquid crystal molecules in the liquid crystal layer substantially vertically to the substrate surface. |
