Abstract

With respect to a display device having an external compensation function, a monitor time can be shortened without increasing the number of wiring lines. A pixel circuit in an i-th row and a j-th column includes an organic EL element (display element), a writing control transistor, a drive transistor, a monitor control transistor, and a holding capacitor. A control terminal of the drive transistor is connected to a data signal line S(j) in the j-th column via the write control transistor. The monitor control transistor includes a first conduction terminal connected to a second conduction terminal of the drive transistor, and a second conduction terminal connected to a data signal line S(j+1) in a (j+1)-th column.
