Claim 9:
10. The display device according to claim 8,
wherein the data signal line drive circuit includes a current measuring unit corresponding to each of the plurality of data signal lines and configured to measure a current flowing through each of the plurality of data signal lines,
when the characteristic of display element included in the i-th row is detected, by the monitor control line drive circuit turning the monitor control transistor included in the i-th row to the an state, a first terminal of a display element included in a pixel circuit in the i-th row and a z-th column (where z is an integer of 1 or more and n—1 or less) is connected to a current measuring unit corresponding to a data signal line in a (z+1) column, and a first terminal of the display element included in the pixel circuit in the i-th row and the (z+1) column is connected to a current measuring unit corresponding to a data signal line in a (z+2) column, and
the data signal line drive circuit applies a current measurement potential as a data signal configured to measure a current representative of the characteristic of the display element to both of the data signal line in the (z+1) column and the data signal line in the (z+2) column.
