摘要： A liquid crystal display device includes: a plurality of scan lines and signal lines on one of a pair of substrates arranged to be opposed to each other with a liquid crystal layer sandwiched therebetween, the scan lines and signal lines extending in different directions; and an orientation film, pixel electrode, insulating layer and common electrode, the orientation film being rubbed in a rubbing direction having a given inclination with respect to a pixel arrangement direction. The pixel electrode is partitioned by the scan lines and signal lines and has subpixels made up of first and second regions. The first region has a plurality of slit-shaped openings having a given inclination in a first direction with respect to the rubbing direction. The second region has a plurality of slit-shaped openings having a given inclination in a second direction with respect to the rubbing direction.

摘要： According to one embodiment, a sensor-equipped display device includes first electrodes and a detection electrode. The first electrodes constitute sensor drive electrodes by being supplied with sensor drive signals separately and sequentially or sensor drive electrodes by simultaneously supplying the sensor drive signals to the first electrodes adjacent to each other. A width of the sensor drive electrode including the first electrode on the edge is smaller than a width of the other sensor drive electrode not including the first electrode on the edge.

摘要： A performance of a display device having an input device is improved. A display device includes: an electro-optical layer; a first driving electrode and a second driving electrode which drives the electro-optical layer; a driver chip which outputs a video signal; a switch circuit which is arranged outside the driver chip, which selects a potential to be supplied to the second driving electrode, and which includes a first switch element and a second switch element; a shift register circuit connected to the switch circuit; and a detection circuit which detects that an object is close or in contact. Each of the first switch element and the second switch element is selectively turned ON or OFF by the shift register circuit. The detection circuit is electrically connected to the first switch element and the second switch element.

摘要： A liquid crystal display device includes a panel unit and a driving unit driving the panel unit. The driving unit includes as operation modes a first mode in which a detection operation of a first external object is performed in units of a divided region obtained by dividing an entire surface of a touch region of the panel unit and a second mode in which a detection operation of a second external object is performed on the entire surface of the touch region of the panel unit. The first mode is a mode detecting, in units of the divided region of the panel unit, a contact position of the first external object with each divided region, and the second mode is a mode detecting, on the entire surface of the panel unit, whether or not the second external object approaches the entire surface.
