Abstract
An apparatus includes a pixel that includes a current path including a light emitting element and a first transistor, a second transistor, and a third transistor connected to a signal wire. One of source and drain regions of the second transistor is connected to one node of the light emitting element and a first power supply. One of source and drain regions of the third transistor is connected to a gate electrode of the first transistor. An isolation portion is disposed between a first conductivity type first diffusion region that makes up one of the source and drain regions of the second transistor and a first conductivity type second diffusion region that makes up one of the source and drain regions of the third transistor. A depth of the first diffusion region is greater than a depth of the second diffusion region.
