Abstract
A liquid crystal display panel () includes a pair of substrates arranged, facing each other, a liquid crystal layer provided between the pair of substrates, and a frame-like sealing member () configured to bond the pair of substrates with each other and enclose the liquid crystal layer. A cavity forming wall () is provided on one of the pair of substrates between the liquid crystal layer and the sealing member () and is configured to form a cavity region (C) therein by an upper end of the cavity forming wall contacting the other of the pair of substrates. The cavity region (C) is configured so that, when an excessive amount of a liquid crystal material which foims the liquid crystal layer is enclosed, the cavity forming wall is destroyed to cause a portion of the liquid crystal material to flow into the cavity region (C).
