A display apparatus comprising:

• a display module array comprising a plurality of display modules horizontally arranged in an M*N matrix;
• and
• an optical layer configured to cover each of the plurality of display modules vertically,
• wherein each of the plurality of display modules comprises:
• a substrate comprising a mounting surface, on which a plurality of light emitting devices is mounted, and a side surface;
• a base layer bonded to the optical layer in a first direction, and covering the mounting surface in a direction opposite to the first direction to protect the plurality of light emitting devices;
• and
• a light absorbing end member covering the side surface of the substrate and at least a portion of a side end of the base layer, the light absorbing end member configured to prevent light, emitted from the plurality of light emitting devices, from passing through the side end of the base layer.
