ABSTRACT:
A liquid crystal display includes a first and a second transparent substrates facing to each other, a liquid crystal layer, a first polarizer, a second polarizer, and a first half wave plate. The liquid crystal layer is interposed between the first and the second transparent substrates. The first polarizer is positioned next to the first transparent substrate and opposite the liquid crystal layer, and the second polarizer is positioned next to the second transparent substrate and opposite the liquid crystal layer. The first half wave plate is provided between the first transparent substrate and the first polarizer to enable the liquid crystal display to have a normally black mode.
