Liquid crystal display
First Claim
1. A liquid crystal display device comprising:
- a liquid crystal cell with liquid crystals sealed therein between, sandwiched between two transparent substrates having an electrode on each of inner surfaces thereof facing each other;
an only absorption-type polarizing film disposed on a visible side of the liquid crystal cell for a polarizing film; and
an only reflection-type polarizing film disposed on a side of the liquid crystal cell, opposite from the visible side thereof for a polarizing film;
said absorption-type polarizing film is a polarizing sheet absorbing light linearly polarized in the direction orthogonal to the transmission axis thereof;
said reflection-type polarizing film is a polarizing sheet reflecting light linearly polarized in the direction orthogonal to the transmission axis thereof, wherein a color filter is disposed on a side of the reflection-type polarizing film, opposite from the liquid crystal cell.

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, an absorption-type polarizing film disposed on the visible side of the liquid crystal cell, a reflection-type polarizing film disposed on the side of the liquid crystal cell, opposite from the visible side. The absorption-type polarizing film is a polarizing sheet absorbing a light linearly polarized in the direction orthogonal to the transmission axis thereof while the reflection-type polarizing film is a polarizing sheet reflecting a light linearly polarized in the direction orthogonal to the transmission axis thereof. A light reflection film or a color filter may preferably be disposed under the reflection-type polarizing film. Further, a light diffusing layer or a light diffusing film may preferably be disposed on the visible side of the absorption-type polarizing film.
