Abstract: A display unit includes sub-pixels that each have a light emitting element, a capacitor, a first transistor that writes a video signal potential to the capacitor, and a second transistor that provides a drive current to the light emitting element based on a voltage stored in the capacitor. Each first transistor has a channel width W and channel length L, such that a width to length ratio is W/L. The width to length ratio W1/L1 of one of the first transistors is different than a width-to-length ratio W2/L2 of at least one other of the first transistors.
