Abstract:
A liquid crystal display device comprising:a liquid crystal panel comprising a pair of opposing transparent substrates each having an alignment film on an inner surface thereof, at least one of said pair of opposing transparent substrates having pixel electrodes on said inner surface thereof, a liquid crystal layer sandwiched between said alignment films, and a pair of polarizers, a first polarizer of said pair of polarizers being disposed in front of said liquid crystal layer and a second polarizer of said pair of polarizers being disposed behind said liquid crystal layer; a driving circuit for supplying voltages to said liquid crystal panel in accordance with display signals; and a backlight having a line light source and disposed behind said liquid crystal panel; wherein each alignment direction of said alignment films is parallel with a polarizing axis of one of said first and second polarizers of said pair of polarizers adjacent thereto; and said polarizing axis of another of said first and second polarizers of said pair of polarizers is perpendicular to a longitudinal axis of said line light source; and wherein adverse effects due to birefringence in said transparent substrates caused by heat from said line light source is suppressed.
