Claim Text:
1. A current drive type display device, comprising: a plurality of pixel circuits each including a light emitting element and disposed in a row direction and a column direction; a plurality of scanning signal lines each connected to the pixel circuits in the same row; a plurality of data signal lines each connected to the pixel circuits in the same column; one or more control lines each connected to the pixel circuits in a plurality of rows; one or more second control lines each connected to the pixel circuits in the plurality of rows; one or more power supply lines each connected to the pixel circuits in the plurality of rows; a drive circuit configured to drive the plurality of scanning signal lines, the plurality of data signal lines, the one or more control lines, and the one or more second control lines; and a power supply circuit configured to selectively apply a plurality of potentials to the one or more power supply lines, wherein the drive circuit and the power supply circuit are configured to simultaneously perform initialization to the pixel circuits in the plurality of rows, simultaneously perform threshold detection to the pixel circuits in the plurality of rows, sequentially write data to the pixel circuits row by row, and perform a control to make the light emitting elements included in the pixel circuits in the plurality of rows emit light in the same period, each of the pixel circuits further includes: the other end of the light emitting element is connected to a conductive member having a fixed common potential, the power supply circuit is configured to selectively apply three kinds of potentials to the one or more power supply lines, and each of the pixel circuits is configured to be controlled such that
