Abstract
A light emitting device in which a pixel is arranged is provided. The pixel includes a light emitting element, a first transistor configured to supply, to the light emitting element, a current corresponding to a luminance signal, and a second transistor configured to supply the luminance signal to a gate electrode of the first transistor. Diffusion regions respectively functioning as a source region and a drain region of the second transistor are of a first conductivity type, and a gate electrode of the second transistor is of a second conductivity type opposite to the first conductivity type.
