  • LCD cell construction by mechanical thinning of a color filter substrate
    Patent number: 6816225
    Abstract: A display device and method for fabricating a liquid crystal cell are disclosed. A liquid crystal cell includes a first substrate, and a second substrate attached to the first substrate. The first substrate has a same thickness as the second substrate. The first substrate is lapped at a first rate while concurrently lapping the second substrate at a second rate, which is different from the first rate. The first substrate and the second substrate are thinned to different thicknesses. The thinner of the first and second substrates is provided on a viewer side of a collimate and post diffuse type liquid crystal cell to reduce depixelization.
    Type: Grant
    Filed: June 26, 2001
    Date of Patent: November 9, 2004
    Assignee: International Business Machines Corporation
    Inventors: Evan George Colgan, Fuad Elias Doany, Tomohito Jounai, Satoshi Maruyama, Hideo Ohkuma, Rama Nand Singh, Masaru Suzuki
