Abstract
The liquid crystal display device comprises a liquid crystal cell with liquid crystals sealed thereinbetween, sandwiched between two transparent substrates having an electrode on each of the inner surfaces thereof facing each other, a first reflective polarizing film disposed on the visible side of the liquid crystal cell, a second reflective polarizing film disposed on the side of the liquid crystal cell, opposite from the visible side, and a light absorption film disposed on the side of the second reflective polarizing film, opposite from the visible side. The first reflective polarizing film as well as the second reflective polarizing film is a polarizing sheet reflecting a light linearly polarized in the direction orthogonal to the transmission axis thereof. A light absorption film and/or a backlight may preferably be disposed under the second reflective polarizing film. Further, an absorption-type polarizing film or a light diffusion layer may preferably be disposed on the visible side of the first reflective polarizing film.
