A driver circuit for driving optical elements which is applied to a pixel driver circuit of the display device in this invention comprises a first current path with one end connected to the optical elements and the other end connected to a drive power supply; a second current path electrically connected to the first current path; a write-in control circuit which flows the write-in current having a predetermined current value in the direction of the other end side from the one end side of the first current path via the second current path; a charge storage circuit which stores the electric charge accompanying the write-in current flowing in the first current path; a drive control circuit which supplies the drive current to the optical elements via the first current path has a current value corresponding to the current value of the write-in current and drives these optical elements based on the electric charge stored in the charge storage circuit; and has a first timing operation in which the electric charge of the write-in current flowing in the first current path is stored by the write-in control circuit according to the write-in current in the charge storage circuit; and a second timing operation which supplies the drive current to the optical elements which does not overlap the time period of the first timing operation.
