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.
