Tsutomu Seino has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6781656
    Abstract: The liquid crystal display device comprising a pair of substrates with alignment layers formed thereon, and a liquid crystal filled between the substrates. Each pixel has pixel display portions CA, CB and non-display portions DA, EA, DB, EB. The pixel display portions are treated for realizing alignment in a different manner from the non-display portions and the alignment of the pixel display portions is controlled by the alignment of the non-display portions. Moreover, the alignment treatment is executed by the irradiation with ultraviolet rays in an inclined direction.
    Type: Grant

  • Publication number: 20030043336
    Abstract: The invention has an object to provide a liquid crystal display in which a wide angle of view is obtained and a response time at a halftone can be shortened by regulating an alignment orientation of a liquid crystal by the use of a polymer fixation system in which a liquid crystal layer containing a polymerizable component is sealed between substrates, and the polymerizable component is polymerized while a voltage is applied to the liquid crystal layer to fix a liquid crystal alignment. A liquid crystal layer containing a polymer for regulating a pretilt angle of a liquid crystal molecule and a tilt direction at a time of driving is sealed between two substrates arranged opposite to each other.

  • Publication number: 20020159018
    Abstract: In a liquid crystal display device, liquid crystal molecules are oriented in a vertical direction to the first substrate and the second substrate by the first molecule orientation film and the second molecule orientation film, respectively, in a non-driving state. And, a structural pattern is formed so as to extend in a first direction parallel to a surface of the liquid crystal layer and so as to form, in a driving state, an electric field periodically changing in a second direction that is parallel to the liquid crystal layer and vertical to the first direction. Then, the liquid crystal molecules substantially tilt in the first direction in the driving state.
