    Abstract: A display module includes a substrate; light emitting diodes, first connection pads, second connection pads, and side wirings. The light emitting diodes are arranged on one surface of the substrate. The first connection pads are formed on the one surface of the substrate. The second connection pads are formed on an opposite surface of the one surface. The side wirings are formed on each of a first edge of the substrate and a second edge of the substrate that is adjacent to the first edge. The side wirings electrically couple the first connection pads on the one surface of the substrate with respective ones of the second connection pads on the opposite surface.
