Patents by Inventor Yumiko Tatemori

Yumiko Tatemori 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: 7872708
    Abstract: The problem to be solved is to suppress image quality degradation caused by polarizers and provide improved light fastness. To solve the above problem, the embodiment of the present invention is a liquid crystal display device. The liquid crystal display device includes a driving-side substrate 1 on which a drive transistor 5, pixel electrode 6 and orientation film are formed. The liquid crystal display device further includes an opposed-side substrate 2 on which an opposed electrode and orientation film are formed. The liquid crystal display device still further includes liquid crystal 4 filled between the pixel electrode 6 of the driving-side substrate 1 and opposed electrode of the opposed-side substrate 2. The liquid crystal display device still further includes a reflective inorganic polarizer 3 formed between the drive transistor 5 and pixel electrode 6 of the driving-side substrate 1.

  • Patent number: 7852448
    Abstract: A liquid crystal display device includes a drive substrate, a counter substrate, a spacer, a liquid crystal layer, and an aperture pattern. The drive substrate is configured to have arranged pixel electrodes. The counter substrate is configured to have a counter electrode common to a plurality of pixels. The spacer is configured to have a column shape and be interposed between the drive substrate and the counter substrate that are so disposed that the pixel electrodes and the counter electrode face each other. The liquid crystal layer is configured to be provided and sealed between the drive substrate and the counter substrate. The aperture pattern in which the spacer is enclosed is provided in the counter electrode.
