Abstract: A display module includes an insulating substrate and a plurality of pixels each located on the insulating substrate and including a light-emitting element layer. The insulating substrate includes a display area where the plurality of pixels are disposed, a picture-frame area outside the display area, an outer area that is in contact with an opposite side of the picture-frame area from the display area, and a plurality of terminals located on the outer area and arranged in a direction. The outer area includes a narrowed portion whose length in the direction is shorter than a length of the display area in the direction.

Abstract: The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.
