Abstract

The display device includes drive circuitsprovided in correspondence to the gate lines, respectively, and alternately switches a scanning period for scanning the gate lines and a non-scanning period during one vertical scanning period. The drive circuitincludes netA(n), an output switching element Mconnected to netA(n), and a reset circuit R. The output switching element Mapplies a selection voltage to the gate line GLn. The potential of netA(n) changes between a first potential that is equal to or higher than a threshold voltage of the output switching element M, and a second potential that is lower than the first potential. In the drive circuitwherein a period while netA(n) thereof has the second potential overlaps with the non-scanning period, the reset circuit R resets the potential of netA(n) to the second potential, before the resumption of the scanning period after the non-scanning period.
