Latest Patents
Yoshiro Katayama holds a patent for a domain divided liquid crystal display device with a particular pretilt. This invention involves a liquid crystal display device that comprises different liquid crystal aligning domains in each of a plurality of unit regions. The design aims to improve the characteristics of the viewing angle. In at least one of the liquid crystal aligning domains, the molecules of the liquid crystal near the first alignment layer are aligned in a first pretilt direction and at a first pretilt angle. Conversely, the molecules near the second alignment layer are aligned in a second pretilt direction, generally opposite the first, and at a second pretilt angle. The first pretilt angle is larger than the second, allowing the liquid crystal molecules located between the first and second plates to rise in accordance with the first pretilt angle when voltage is applied. This feature can be widely utilized in combination with a suitably selected arrangement of the other liquid crystal aligning domains, thereby reducing rubbing steps and photolithography steps.
