Abstract
A light-emitting device has a plurality of data lines and a plurality of pixel circuits. Each of the plurality of pixel circuits includes a light-emitting element that has a first electrode and a second electrode and that emits light having an intensity depending on the amount of driving current; a driving transistor that supplies the driving current to the first electrode; a holding transistor that supplies a driving signal supplied via the data lines to the driving transistor; and a connecting line that connects the driving transistor to the holding transistor. The second electrode is formed in a region different from a region in which the data lines are formed such that the second electrode is not opposite to some or all of the data lines.
