Title: Tablet integrated liquid crystal display apparatus with less parallax

Abstract: In a tablet integrated type liquid crystal display apparatus, a first transparent substrate is provided on a view side. The first substrate is a plastic substrate having a thickness equal to or thinner than 0.6 mm, and a counter electrode is formed on the first substrate. A second substrate on which a driving layer composed of switching elements and pixel electrodes respectively connected to the switching elements is formed. The second substrate is a glass substrate having a thickness in a range of 0.6 mm to 1.1 mm. A guest host liquid crystal layer sandwiched by the first substrate and the second substrate such that the guest host liquid crystal is driven by a voltage applied between the counter electrode and the pixel electrode. A tablet electrode layer may be provided between the first substrate and the counter electrode. Alternatively, a tablet electrode layer may be provided on the first substrate on an opposite side of the counter electrode. In this case, a protecting film is provided on the tablet electrode layer. In addition, a tablet electrode layer may be provided between the second substrate and the driving layer such that the tablet electrode layer is isolated from the driving layer.
