摘要
An LCD apparatus includes a first polarizer, a half-wavelength retardation plate, a liquid crystal unit and a second polarizer. The LCD apparatus further has a backlight module for generating first polarized light. The first polarizer is disposed downstream of the backlight module, and the first polarizer has a transmission axis. The half-wavelength retardation plate is disposed between the backlight module and the first polarizer. Second polarized light parallel to the transmission axis is generated from the first polarized light passing through the half-wavelength retardation plate. The second polarizer is disposed downstream of the first polarizer. The liquid crystal unit is disposed between the first polarizer and the second polarizer, and the second polarized light emits out of the LCD apparatus through the first polarizer, the liquid crystal unit and the second polarizer.
