Classification: CPC G | IPC G

Claim 17:
18. A display panel comprising:
a light emitting device;
a driving transistor configured to drive the light emitting device;
a bias transistor configured to control a connection between a drain electrode or a source electrode of the driving transistor and a power supply line; and
a data supply transistor configured to control a connection between the source electrode or the drain electrode of the driving transistor and a data line according to a scan signal supplied from a scan line,
wherein in a non-display area located outside a display area in which an image is displayed, the scan line and the power supply line are disposed adjacent to each other, and
wherein a driving period includes a first frame and a second frame different from the first frame,
wherein the first frame includes a first refresh period in which a first data voltage is written and a first reset period in which the first data voltage is maintained,
wherein the second frame includes a second refresh period in which a second data voltage is written and a second reset period in which the second data voltage is maintained, and
wherein a first voltage pulse of the bias voltage during the first refresh period and a second voltage pulse of the bias voltage during the second refresh period are different from each other.
