1. An electro-optical device, comprising:
a first scanning line disposed in an i-th row in a display region;
a first pixel circuit provided corresponding to the first scanning line and a first data line provided in a k-th column in the display region, and configured to be brought into an optical state in accordance with a voltage of the first data line when the first scanning line is selected;
a second scanning line disposed in an (i+1)-th row in the display region;
a second pixel circuit provided corresponding to the second scanning line and the first data line, and configured to be brought into an optical state in accordance with a voltage of the first data line when the second scanning line is selected; and
a scanning line drive circuit configured to supply a scanning signal to the first scanning line and the second scanning line,
wherein
i and k are integers,
in a period, in which the first scanning line and the second scanning line are selected, of a first subframe period of a frame period,
a data signal of a voltage corresponding to the i-th row and the k-th column of first image data in the first subframe period is output, and
in a period, in which the first scanning line and the second scanning line are selected, of a second subframe period of the frame period,
a data signal of a voltage corresponding to the (i+1)-th row and the k-th column of second image data in the second subframe period is output;
wherein
the scanning line drive circuit includes a first holding circuit holding information for setting each of the first scanning line and the second scanning line to a primary or a secondary, and
when information for specifying selection of the scanning line set to the primary is supplied,
supplies the primary scanning line with a scanning signal indicating that the primary scanning line is to be selected, and
supplies the scanning line set to the secondary with a scanning signal indicating that the scanning line set to the secondary is to be selected; and
wherein
each of the first pixel circuit and the second pixel circuit includes a first transistor, a second transistor, a third transistor, a fourth transistor, and a display element,
the first transistor
includes a gate node, a source node, and a drain node, and
causes a current in accordance with a voltage between the gate node and the source node to flow to the display element via the fourth transistor,
the second transistor is provided between the first data line and the gate node of the first transistor, and brought into an on-state or an off-state in accordance with selection or non-selection of a scanning line,
the third transistor is provided between the data line and the drain node of the first transistor, and
the fourth transistor is provided between the drain node of the first transistor and the display element,
in the first subframe period,
there is a period in which the gate node and the drain node of the first transistor in the first pixel circuit are electrically coupled,
there is not a period in which the gate node and the drain node of the first transistor in the second pixel circuit are electrically coupled,
and in the second subframe period there is not a period in which the gate node and the drain node of the first transistor in the first pixel circuit are electrically coupled, and
there is a period in which the gate node and the drain node of the first transistor in the second pixel circuit are electrically coupled.
