1. A display unit comprising:
a plurality of pixels, respective ones of the plurality of pixels consisting of first, second, third and fourth sub-pixels including an R sub-pixel, a G sub-pixel, a B sub-pixel and a W sub-pixel, respective ones of the sub-pixels each including a light emitting element, a capacitor, a first transistor configured to write a signal potential to the capacitor, and a second transistor configured to provide a drive current to the light emitting element based on a voltage stored in the capacitor, the capacitor including a first terminal connected to a gate of the second transistor and a second terminal connected to a source or drain of the second transistor,
wherein the first transistor of each of the sub-pixels has a width-to-length ratio W/L, and
a width to length ratio W1/L1 of the first transistor of the first sub-pixel is different than a width-to-length ratio W2/L2 of the first transistor of the second sub-pixel.
