Abstract:
1. A display device, comprising: a plurality of pixels in a matrix, wherein at least one of the plurality of pixels comprises: a light emitting element; a drive transistor; and a pixel capacitor, wherein the drive transistor is configured to allow a drive current to flow to the light emitting element according to a signal potential stored in the pixel capacitor, wherein a feedback current, the feedback current being a part of a drain current of the drive transistor, is configured to flow to the pixel capacitor via the drive transistor to subtract a voltage from an input voltage stored in the pixel capacitor before the drive transistor allows the drive current to flow, a source potential of the drive transistor being altered during a discharge of the pixel capacitor, and wherein the drive transistor has a size ratio W/L of at least 0.5, where W is a channel width and L is a channel length.
