Abstract
A liquid crystal display panel comprising a liquid crystal cell with liquid crystals sealed therein, sandwiched between two transparent substrates having an electrode on each of the inner surfaces thereof facing each other, a first polarizing film disposed on the visible side of the liquid crystal cell, a second polarizing film disposed on the opposite side of the liquid crystal cell from the visible side, and a light absorbing film disposed on the opposite side of the second polarizing film from the visible side. The first polarizing film is a reflection-type polarizing film reflecting the light linearly polarized in the direction orthogonal to the transmission axis thereof, and the second polarizing film is an absorption-type polarizing film or color polarizing film each absorbing the light linearly polarized in the direction orthogonal to the transmission axis thereof. A transflective reflector and/or a color filter may preferably be disposed between the second polarizing film and a light source.
