A display device capable of displaying a picture of vivid colors
maintaining a good balance of colors and a good balance of light-emitting
brightnesses of the EL elements. The widths of the detour wirings
supplying current to the power source feed lines are increased for those
EL elements into which a current of a large density flows. This
constitution decreases the wiring resistances of the detour wirings,
decreases the potential drop through the detour wirings, and suppresses
the amount of electric power consumed by the detour wirings.
