摘要： A display apparatus includes a basement, a display functional layer, a first electrode, a guard electrode, and a detection controller. The basement has a first surface and a second surface opposite to the first surface. The display functional layer is arranged on the side of the second surface of the basement. The first electrode is arranged between the basement and the display functional layer and detects an object in contact with or in proximity to the first surface. The guard electrode is arranged between the first electrode and the basement and supplied with a guard signal. The guard signal suppresses a change in capacitance generated between the first electrode and the guard electrode. The detection controller is a controller to which a signal based on a change in capacitance of the first electrode is output from the first electrode.

摘要： A pixel electrode formed into a slit structure with striped electrodes opposed to each other for a zero rubbing angle can provide fast response since rotational directions of the liquid crystals become opposite at both sides of the slit in the striped electrodes. The electrode structure, however, poses a problem of low transmittance. Provided is a liquid crystal display device of IPS-Pro scheme including a pixel electrode with one pair of striped electrodes. The first striped electrode includes a short electrode section and long electrode sections, and the second striped electrode also includes a short electrode section and long electrode sections. The long electrode sections of the first striped electrode are disposed adjacently to those of the second striped electrode. Liquid crystals are aligned in a lengthwise direction of the striped electrodes.
