Liquid crystal display device |
| abstract |
The present invention provides a liquid crystal display device that has a higher contrast ratio in a wide viewing angle and that can be easily produced at low cost. The present invention is a liquid crystal display device, including in the following order:n a first polarizer; a first quarter-wavelength plate (nx>ny≧nz); a liquid crystal cell; a second quarter-wavelength plate having an Nz coefficient substantially the same as that of the first quarter-wavelength plate; a birefringent layer (II) (nx<ny≦nz); and a second polarizer, wherein the first birefringent layer (I) has an in-plane slow axis forming an angle of about 45° with an absorption axis of the first polarizer; the second birefringent layer (I) has an in-plane slow axis substantially orthogonal to the in-plane slow axis of the first birefringent layer (I); the second polarizer has an absorption axis substantially orthogonal to the absorption axis of the first polarizer; the birefringent layer (II) has an in-plane fast axis substantially orthogonal to the absorption axis of the second polarizer; and the LC cell displays a black screen by aligning liquid crystal molecules in the liquid crystal layer substantially vertically to the substrate surface. |
