When a signal inputted to a pixel is erased by setting potentials of a gate terminal and a source terminal of a driving transistor to be equal, a current slightly flows through the driving transistor in some cases, which leads to occur a display defect. The invention provides a display device which improves the yield while suppressing the increase in manufacturing cost. When a potential of a scan line for erasure is raised, a potential of the gate terminal of the driving transistor is raised accordingly.

A feedforward control section computes, on the basis of a target current absolute value, a voltage limit value of a motor drive circuit, and a rotational speed ωr of a motor, a phase angle of a voltage vector which represents the output voltage of the motor drive circuit by a d-q coordinate system, the phase angle being a phase angle in relation to the d-axis of the d-q coordinate system. A feedback control section computes a phase angle based on a deviation between the target current absolute value and the actual current absolute value. A PWM control signal generation section outputs PWM control signals such that the motor drive circuit outputs a three-phase drive voltage whose electrical angle is advanced by a phase angle. Thus, in the case where a large reverse input is applied to a steering mechanism, the motor is caused to generate a large torque to thereby prevent the steering wheel from being rotated.
