Abstract
A liquid crystal display apparatus includes a liquid crystal display device and a touch panel. The display device includes first and second substrates positioned on observation and opposite sides, respectively, a liquid crystal layer interposed between the substrates, a first electrode provided on one of opposed inner surface sides of the substrates, a second electrode provided on an inner surface side of one of the substrates and supplies a voltage between itself and the first electrode to apply an electric field to the liquid crystal layer, and two polarizing plates respectively arranged on the observation and opposite sides on the other side of the substrates. The touch panel includes an electroconductive film arranged on an outer surface of the substrate or the polarizing plate on the observation side, and detects a specified position on the electroconductive film based on a voltage previously applied thereto and a voltage measured at the specified position.
