    Abstract: According to one embodiment, a display device includes a base, a display unit containing pixels, a power supply circuit, a touch controller and a switching circuit disposed between the display unit, the power supply circuit and the touch controller. The pixels each includes a pixel circuit and a display element including a lower electrode connected to the pixel circuit, an upper electrode disposed to oppose the lower electrode and an organic layer including a light-emitting layer disposed between the lower electrode and the upper electrode. The upper electrode is connected to the switching circuit, and the switching circuit selectively switches between connecting the upper electrode to the power supply circuit and connecting the upper electrode to the touch controller.

    Abstract: Provided is a display device including a plurality of pixels at least one of which has a first transistor and a light-emitting element. The first transistor includes a gate electrode, a gate insulating film over the gate electrode, an oxide semiconductor film over the gate insulating film, and a first terminal and a second terminal electrically connected to the semiconductor film. The second terminal is electrically connected to the light-emitting element. A region in which the first terminal overlaps with the gate electrode can be smaller than a region in which the second terminal overlaps with the gate electrode.

    Abstract: Disclosed is a display device including: a driving transistor, a first switching transistor, and a pixel transistor each having a gate and a pair of terminals; a storage capacitor having a pair of terminals; and a light-emitting element having an input terminal and an output terminal. One terminal of the driving transistor is electrically connected to one terminal of the pixel transistor. The other terminal of the driving transistor is electrically connected to one terminal of the first switching transistor and the input terminal of the light-emitting element. The other terminal of the first switching transistor is electrically connected to the gate of the driving transistor and one terminal of the capacitor. The one terminal of the capacitor overlaps with an active region of the driving transistor.

    Abstract: According to one embodiment, a display device includes a substrate, first and second insulating layers, first and second pixel electrodes, first and second organic layers, first and second feed lines, first and second partitions, and a common electrode including first and second parts covering the first and second organic layers. The first organic layer is between the partitions. The second feed line and the second partition are located between the organic layers. The partitions are shaped such that a width of an upper part is greater than a width of a lower part. The first part is in contact with the first feed line between the first partition and the first organic layer.
