    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: By a drive method, for each of a plurality of display pixels each including an EL element, a capacitor, a drive transistor, an enable switch, and a switch, a period T21 is started by switching only the enable switch to an electrically conductive state before a period T22 in which the drive transistor is initialized, and the period T22 following the period T21 is started by switching the switch to an electrically conductive state. The period T21 is longer than a period T24 in which a threshold voltage of the drive transistor is compensated.

    Abstract: A display device includes: a pixel region in which plural pixels, each including a light emitting element, a capacitor, a drive transistor, and a switch transistor, are arranged in rows and columns; scanning lines; signal lines; and parasitic capacitance which occurs between a source node of the light emitting element of each of the plural pixels and a signal line among the signal lines, wherein when images having different grayscales are displayed in the pixels on adjacent rows which are a 1st-row pixel and a 2nd-row pixel, a difference between a gate-source voltage of the drive transistor of the 1st-row pixel and a gate-source voltage of the drive transistor of the 2nd-row pixel is less than a voltage value of one grayscale, the difference being represented by ΔVdata×Cad/(Cs+Cad+Coled).
