Liquid crystal display device and liquid crystal display apparatus

摘要

A liquid crystal display device includes first and second substrates arranged to face each other with a predetermined gap, and a liquid crystal layer sealed between the first and second substrates. The first substrate includes pixel electrodes and thin-film transistors connected with the pixel electrodes. The transistors are turned on based on a scanning signal from scanning lines to electrically connect the pixel electrodes to signal lines. The second substrate has an opposed electrode, which forms pixels in areas facing the pixel electrodes. The device also has a touch input contact point provided on either the pixel electrodes or the opposed electrode to correspond to a previously selected pixel. The contact point protrudes at a height smaller than the gap between the first and second substrates and is brought into conduction by flexural deformation caused by a pressing force of a touch onto the first or second substrates.
