Abstract
A liquid crystal display apparatus includes a first protective layer, a first polarizing layer, a second protective layer, an active device array substrate, an opposite substrate, a twisted nematic liquid crystal layer, a third protective layer, a second polarizing layer and a fourth protective layer. The first polarizing layer is disposed between the first and the second protective layers; the active device array substrate is disposed over the second protective layer. The twisted nematic liquid crystal layer is disposed between the opposite substrate and the active device array substrate. The third protective layer is disposed on the opposite substrate, and the second polarizing layer is disposed between the third and the fourth protective layers. The second protective layer has an in-plane and an out-of-plane retardation values. The in-plane retardation value is between 1 and 10 nanometers, and the out-of-plane retardation value is between 50 and 130 nanometers.
