Abstract
An active matrix type liquid crystal display system having a plurality of switching elements, the active matrix type liquid crystal display system including a pair of substrates, signal electrode lines and scanning electrode lines formed on one of the pair of the substrates and crossing each other in a matrix form. A plurality of pixels are delimited by the signal electrode lines and the scanning electrode lines and a liquid crystal layer is interposed between the pair of the substrates. Each pixel of the pixels includes an electrode structure for generating an electric field having a component substantially in parallel with one of the substrates upon application of at least one predetermined voltage thereto, and an optical structure for obtaining a voltage vs. brightness characteristic where the voltage to obtain a minimum brightness is greater than zero.
