Abstract
A luminescence device according to the present invention includes a plurality of pixels arranged in a row direction and a column direction. Each pixel includes a luminescence driving transistor, a pixel electrode, a luminescence layer formed above the pixel electrode, and an opposing electrode formed above the luminescence layer. Current supply lines La connect the pixels in the row direction and are arranged to extend in the same direction. Adjoining current supply lines La are electrically connected to each other by a drain electrode of the luminescence driving transistor of the pixel positioned between these current supply lines La. Therefore, adjoining current supply lines La are made to be at the same potential.
