An organic EL display module includes a plurality of current supply lines extending to a first side of a substrate from a display region, a currently supply bus line connecting with a plurality of current supply lines on a peripheral region of the first side of the substrate, and a terminal pad formed on a peripheral region of a second side of the substrate which is opposite to the first side of the substrate. A current supply wiring connects the current supply bus line and the terminal pad, and the current supply wiring is provided on a peripheral region of a third side which is adjacent to the first and second side.
