Abstract
A liquid crystal display panel includes: a pair of substrates; a cylindrical spacer configured to hold a gap between the pair of substrates, and a liquid crystal which fills the gap. The cylindrical spacer includes a first support portion having a first support surface and a second support portion having a second support surface. The first support portion is provided inside the second support surface so that the first support surface is projected from the second support surface. The second support portion is provided on a major surface of one of the substrates the second support surface from the major surface.
