Abstract: A display device includes: a display unit which includes a plurality of pixels each including an organic EL element; and a control unit which adjust a value of a luminance signal to be supplied to a target pixel to be corrected, such that an actual luminance of the target pixel is equal to a reference luminance, the reference luminance being an actual luminance of a reference pixel obtained when the luminance signal to be supplied to the target pixel is supplied to the reference pixel. The reference pixel has predetermined attenuation characteristics for light emission amount.

Abstract: Pixel circuits each include a write transistor having a gate electrode connected to a write control line, one of a drain electrode and a source electrode connected to a data line for transmitting data voltage corresponding to luminance of the pixel circuit, and the other of the drain electrode and the source electrode connected to a gate electrode of a drive transistor. A compensation circuit includes a compensation transistor connected to a compensation signal line and the write control line. A compensation voltage generation circuit outputs compensation control voltage in accordance with a representative value of data voltage for the pixel circuits. A capacitance of the write control line caused by the compensation transistor and a capacitance of the write control line caused by the write transistors of the pixel circuits have mutually opposite voltage dependence with respect to the representative value of the data voltage for the pixel circuits.

Abstract: An active-matrix display device according to the present disclosure includes a plurality of pixels. Each of the pixels includes: a drive transistor disposed on a substrate; and an organic EL element that is caused by the drive transistor to emit light and includes an AM layer disposed above the substrate and a transparent electrode layer disposed above the AM layer. The active-matrix display device further includes: a source line that supplies data to the pixels; and a power supply line that supplies electric power to the pixels. The power supply line is shared by, among the plurality of pixels, two pixels that are adjacent to each other in a second direction that crosses a first direction in which the power supply line is extended. The source line and the AM layer are disposed not to overlap each other in a plan view of the substrate.

Abstract: A method for driving a display device including a plurality of pixels arranged in rows and columns, each of the pixels including an organic EL device that emits light in accordance with supplied current, a driving transistor that supplies current to the organic EL device, and a storage capacitor connected between the gate of driving transistor and a source or drain thereof, includes causing the organic EL device to emit light by supplying current to the organic EL device; resetting charge of at least one of the storage capacitor and a parasitic capacitance of the organic EL device; and applying a reverse bias voltage between the gate and source of the driving transistor. The resetting is performed between the light emission and the reverse-bias application.
