Abstract
A liquid crystal display device includes a liquid crystal panel having a pair of opposing transparent substrates each having an alignment film on an inner surface thereof, at least one of the substrates having pixel electrodes on the inner surface thereof, a liquid crystal layer sandwiched between the alignment films, and a pair of polarizers, one of which is disposed in front of the liquid crystal layer and another of which is disposed behind the liquid crystal layer; a driving circuit for supplying voltages to the liquid crystal panel in accordance with display signals; and a backlight having a line light source and disposed behind the liquid crystal panel, wherein each alignment direction of the alignment films is parallel with a polarizing axis of one of the polarizers adjacent thereto, and the polarizing axis of the another of the pair of polarizers is perpendicular to a longitudinal axis of the line light source.
