Liquid crystal display panel
First Claim
1. 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 a visible side of the liquid crystal cell;
a second polarizing film disposed on the side of the liquid crystal cell, opposite from the visible side thereof; and
a light source disposed on the side of the second polarizing film, opposite from the liquid crystal cell;
wherein at least one of the electrodes is formed in a pattern of display segments or in a dot-matrix type for indicating information, only one polarizing film is disposed on each side of the liquid crystal cell, and the first polarizing film is a reflection-type polarizing film reflecting the light linearly polarized in a direction orthogonal to a transmission axis of the first polarizing film while the second polarizing film is an absorption-type polarizing film absorbing the light linearly polarized in a direction orthogonal to a transmission axis of the second polarizing film.

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.
