Abstract
Abstract A liquid crystal display apparatus is disclosed which can effectively prevent chipping of a glass substrate or damage to a polarizing plate constituting a liquid crystal panel. The liquid crystal display apparatus comprises a liquid crystal panel including a pair of substrates having transparent electrodes on inner faces thereof, a liquid crystal layer held between the substrates, and a polarizing plate disposed on an outer face of each of the substrates. The liquid crystal panel is supported on a protective frame, and the end faces of the substrates are surrounded by a side wall of the protective frame which has a vertical dimension greater than the overall thickness of the liquid crystal panel. The protective frame and the liquid crystal panel are secured to each other by means of a bonding agent so as to form the liquid crystal display apparatus into a unitary block which is easy to handle.
