Abstract
Systems for displaying images are provided. A representative system comprises a wide viewing angle liquid crystal display with multi-film compensation. A liquid crystal display comprising a first substrate, a second substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate. A first compensation film is interposed between the first polarizer and the first substrate. A second compensation film interposed between the second polarizer and the second substrate. The first compensation film and the second compensation film comprise different birefringence polarities.
