Abstract
A light-emitting device has a plurality of pixel circuits arranged in one direction, each of the plurality of pixel circuits having a light-emitting element that emits light according to the amount of driving current, a driving transistor that supplies the driving current to the light-emitting element, a holding transistor that supplies a data signal supplied via a data line to the driving transistor, and a connecting line that connects the driving transistor to the holding transistor. The holding transistor, the light-emitting element, and the driving transistor are arranged in a direction crossing the arrangement direction of the plurality of pixel circuits. The light-emitting element is provided between the holding transistor and the driving transistor.
