  • 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.

  • Publication number: 20120268708
    Abstract: A liquid crystal display includes: a pair of substrates, which face with each other, wherein at least one of the pair of substrates is made of ultra-thin glass; a liquid crystal member arranged between the pair of substrates; a main seal pattern arranged between the pair of substrates to bond the pair of substrates and to surround and seal the liquid crystal material; and a gap maintaining member, which is arranged to at least a substrate edge in the vicinity of a substrate edge formed by cutting the at least one of the substrates made of the ultra-thin glass, and which maintains a distance between the pair of substrates in a predetermine range.
