Abstract:
A display device including: scanning lines; data lines; pixels provided in a matrix; and a power line, each of the pixels includes: an organic EL device; a drive transistor which converts a data voltage applied to a gate into a drive current; a capacitor which holds a voltage according to the data voltage; a selector transistor having a gate connected to one of the scanning lines and a source connected to the gate of the drive transistor; a selector transistor having a gate connected to the scanning line, a source connected to a drain of the selector transistor, and a drain connected to the data line; and a guard potential transistor having a gate connected to the source of the selector transistor, a source connected to the drain of the selector transistor, and a drain connected to the power line.
