Liquid crystal display device with quarter plates and birefringent layers and liquid crystal having substantially vertical alignments in black state |
摘要 |
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 liquid crystal display device may include polarizers and multiple birefringent layers. A first birefringent layer (I) can have an in-plane slow axis forming an angle of about 45° with an absorption axis of the first polarizer; the second birefringent layer (I) can have an in-plane slow axis substantially orthogonal to the in-plane slow axis of the first birefringent layer (I). |
