  • Liquid crystal display device with main columnar spacers and sub columnar spacers having different area densities
    Patent number: 10197867
    Abstract: A liquid crystal display device of the present invention includes a liquid crystal interposed between a CF substrate that is an ultra-thin glass substrate and a TFT substrate, and a seal pattern having an injection port. Spacer structures are arranged such that the area density thereof is higher in a corner portion farther from the injection port than in a corner portion closer to the injection port.
    Type: Grant
    Filed: October 12, 2016
    Date of Patent: February 5, 2019
    Assignee: Mitsubishi Electric Corporation
    Inventors: Toshiro Taniguchi, Hideo Yabiku, Toshiaki Fujino

  • Liquid crystal display device and method of manufacturing the same
    Patent number: 8873017
    Abstract: A liquid crystal display device includes: first and second glass substrates; a seal pattern placed between the first and second glass substrates to bond the first and second glass substrates together, the seal pattern sealing a liquid crystal material in between the first and second glass substrates and holding the liquid crystal material in a liquid crystal layer; a plurality of columnar spacers placed between the first and second glass substrates in a display region surrounded by the seal pattern and corresponding to a display surface appearing when the liquid crystal display device is in operation, the columnar spacers holding a distance between the first and second glass substrates; and a plurality of gap holding members. The area share of the gap holding members indicating the ratio of a sectional area per unit area is larger than the area share of the columnar spacers.
