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°.

摘要： A laminated phase plate is formed by laminating a first optical phase difference compensation plate, having a retardation between 100 and 180 nm for transmitted light, with a wavelength of 550 nm and a second optical phase difference compensation plate having a retardation between 200 and 360 nm for transmitted light with a wavelength of 550 nm. The optical phase difference compensation plates are arranged so that |&thgr;1−(2×&thgr;2)| is between 80 and 100 degrees. The term &thgr;1 is an angle between a vibration direction of linearly polarized light and a slow axis direction of the first optical phase difference compensation plate when the linearly polarized light, which is visible light and has a fixed plane of vibration, is incident on the second optical phase difference compensation plate. The term &thgr;2 is an angle between the vibration direction of linearly polarized light incident on the second optical phase difference compensation plate and a slow axis direction of the second optical phase difference compensation plate.

摘要： When forming reflection electrodes on a thin film transistor which is a switching element, it is formed on irregular plural bumps, an organic insulating film possessing bumps corresponding to the bumps is formed, and the reflection electrodes are formed thereon. Since the reflection electrodes are formed on the organic insulating film, there is no effect of the thin film transistor, and the reflection electrodes may be formed as largely as possible in a range capable of maintaining the insulation between adjacent reflection electrodes, so that the opening rate may be enhanced to 90% or more.
