Reflective liquid crystal display device and reflective liquid crystal display device incorporating touch panel arranged therefrom |
摘要 |
A reflective color liquid crystal display device with a liquid crystal layer sandwiched between a first substrate having a light reflectibility and a second substrate having a light transmissibility. The liquid crystal layer being composed of twist-aligned nematic liquid crystal having a positive dielectric anisotropy. A circularly polarizing unit, including a single linear polarizer plate, selectively passes either right handed or left handed circularly polarized light out of natural light. The circularly polarizing unit is disposed so that a major surface of the circularly polarizing unit is on a liquid crystal layer side, the circularly polarized light exiting the circularly polarizing unit through the major surface when natural light enters the circularly polarizing unit. Various parameters of the liquid crystal layer are optimized for a liquid crystal layer having a twist angle in the range of 0° to 100°.
