Abstract
An electro-optical device is provided with a plurality of data lines, a plurality of potential lines supplied with a predetermined potential, a driving transistor controlling a current level according to the voltage between the gate and the source, a first storage capacitor which holds the voltage between the gate and a source of the driving transistor, and a light-emitting element. One data line among the plurality of data lines and one potential line among the plurality of potential lines are arranged to be adjacent to each other, and a second storage capacitor holding the potential of the one data line is formed by the one data line and the one potential line.
Claims8
An electro-optical device comprising:
- a first data line;
