Abstract

A liquid crystal display device includes a single liquid crystal panel in which a liquid crystal material is sealed in a clearance between two transparent substrates, at least one light source, and at least one light-conducting plate. The liquid crystal panel includes a transmitting region and a reflecting region. A part of a first surface of the liquid crystal panel is a first display surface for the transmitting region and a part of a second surface of the liquid crystal panel is a second display surface for the reflecting region. A two-sided display is provided from a single liquid crystal panel and a thin and light-weight liquid crystal display device is achieved.
