Patent ID: 8692259

Claim:
A light-emitting device comprising: a data line through which a data signal is transmitted; a power feeding line to which a predetermined potential is applied; a light-emitting element in which a light-emitting layer is interposed between a first electrode and a second electrode; a first transistor having a first gate electrode; a conducting portion that connects the first electrode of the light-emitting element to the first transistor, a second transistor that controls a conduction state between the first gate electrode of the first transistor and a first drain of the first transistor; and a connecting portion, the power feeding line having a first portion and a second portion, the first portion being disposed between the conducting portion and the data line in plan view, the first portion and the second portion extending linearly and a middle portion of the first portion and a middle portion of the second portion crossing each other in plan view, the first gate electrode of the first transistor being connected to the second transistor through the connecting portion, and the first portion of the power feeding line being disposed between the connecting potion and the data line.
