ABSTRACT:
Transmissive liquid crystal displays having response time that can be approximately 2 to approximately 3 times faster than conventional displays. The displays adjust the rubbing angles to above approximately 20 degrees and preferably between approximately 30 and approximately 40 degrees. The displays have fast response times, enhanced brightness and increased gray scale linearity while maintaining wide viewing angle.
