    Abstract: A drive circuit includes a holding capacitor, an element capacitor, and an additional capacitor interposed between one of the source and the drain, and one of the high-potential line and the low-potential line. The drive circuit configured to drive the first light emitter includes a first element capacitor as the element capacitor and a first additional capacitor as the additional capacitor. The driving circuit configured to drive the second light emitter includes a second element capacitor as the element capacitor and a second additional capacitor as the additional capacitor. The first element capacitor is larger in capacitance than the second element capacitor. The first additional capacitor is smaller in capacitance than the second additional capacitor.

    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: In the second area, the lower base surface of the wirings is in contact with the first inorganic insulating film including a stepped portion including upper surfaces having mutually different heights and being adjacent to each other in the second direction, and a stepped surface rising from the upper surfaces except the uppermost surface. The first inorganic insulating film constitutes at least the upper surfaces except the lowest surface, and the stepped surface. The adjacent wirings include a pair of convex portions protruding toward a direction facing each other. One and the other of the pair of convex portions are separated to face each other at a position where the stepped portion does not exist in the second area in the first inorganic insulating film.

    Abstract: A flash phenomenon of OLEDs at the time of power source ON of a display device is suppressed. The OLED emits light when reference potentials VSS and VDD are applied from power source lines to the OLED's cathode and anode respectively. While the anode can be connected to one of the power source line via a driving TFT and a lighting switch, a reset potential VRS can be applied to the anode via a reset switch and the driving TFT. The lighting switch is turned OFF and the reset switch and the driving TFT are turned ON so that VRS is applied to the anode, before starting the application of the reference potentials to the power source lines. Following this state, the application of the reference potentials to the power source lines starts, and thus a normal operation of allowing the OLED to emit light starts.
