A display device according to the present disclosure includes: pixels arranged in a matrix; a data line group that includes a pair of data lines for each pixel column; a data line drive circuit that supplies a positive-phase data signal to one of the pair of data lines, and a negative-phase data signal to the other of the pair of data lines; and an auxiliary drive circuit that is provided for each pair of data lines, and that processes the positive-phase data signal and the negative-phase data signal, in which the auxiliary drive circuit has a dead zone in a region where there is no difference between a positive-phase potential and a negative-phase potential, or where the difference in potential is smaller than a predetermined value. An electronic apparatus according to the present disclosure includes a display device having the configuration described above.

Display device and electronic apparatus

A display device includes: data-line pairs arranged side by side along a first direction; gate lines arranged side by side along a second direction; a display section including pixels each disposed at an intersection of a data-line pair and a gate line and connected to one or both of the data-line pair; a data-line drive circuit supplying a positive-phase data signal to one of the data-line pair and a negative-phase data signal to the other, and allowing the data-line pair to stay in a high-impedance state before writing of an image signal to the pixels; and a short circuit putting the data-line pair in a short-circuit state while the data-line pair stays in the high-impedance state, and then releasing the short-circuit state Following the release of the short-circuit state, the positive-phase data signal or/and the negative-phase data signal are written into the pixel as the image signal.
