Liquid crystal display apparatus

Abstract

A liquid crystal display apparatus arranged with a light guide plate of an illuminating apparatus between two liquid crystal panels for increasing an efficiency of utilizing light of the illuminating apparatus to thereby increase brightness both in a transmission display mode and a reflection display mode. For that object, there is constructed a constitution of providing a first lower polarizer between a first liquid crystal panel and a light guide plate, a second lower polarizer between a second liquid crystal panel and the light guide plate and a reflection-polarizing plate between the light guide plate and the second lower polarizer. Thereby, the efficiency of utilizing light of the illuminating apparatus can be increased. Further, a transmission axis of the first lower polarizer and a reflection axis of the reflection-polarizing plate are aligned in the same direction and a transmission axis of the second lower polarizer is set to make an angle θ (incidentally, θ is an angle other than 90 degrees) relative to the reflection axis of the reflection-polarizing plate. A rate of reflection/transmission of the second liquid crystal panel can freely be set by changing the angle.
