Abstract
A light emitting apparatus comprising a plurality of pixels with different light emitting colors, each of the plurality of pixels includes a light-emitting element configured to emit light with one of at least three different light emitting colors, a driving transistor configured to supply a current to the light-emitting element in accordance with a voltage supplied to a gate, a write transistor configured to supply a signal voltage from a signal line to the gate of the driving transistor, and a capacitance at a connection portion between the driving transistor and the write transistor, wherein the capacitance is different for each light emitting color, and is larger in a pixel of a light emitting color in which a peak current flowing through the light-emitting element is larger.
