Display apparatus having display module and manufacturing method thereof

A display module comprising:

• a substrate having a mounting surface on which a plurality of inorganic light-emitting diodes are mounted, a side surface, and a rear surface being opposite to the mounting surface;
• a front cover bonded with the mounting surface of the substrate and covering the mounting surface of the substrate;
• a metal plate bonded with the rear surface of the substrate;
• a side cover surrounding the side surface of the substrate;
• and
• a side end member covering at least one portion of the side cover and at least one portion of the metal plate, the side end member comprising a first end portion, a second end portion spaced from the first end portion in a direction in which the mounting surface faces, and a side end portion extending from the first end portion to the second end portion and forming a side end;
• wherein the first end portion of the side end member covers at least one portion of the side end of the side cover,
• wherein the second end portion of the side end member contacts the metal plate and is grounded to the metal plate, and
• wherein the side end portion comprises mountains and valleys alternately arranged in the direction in which the mounting surface faces.

A display apparatus comprising:

• a display module array comprising a plurality of display modules arranged in a matrix, wherein each of the plurality of display modules comprises:
• a substrate having a mounting surface on which a plurality of inorganic light-emitting diodes in a first direction are mounted, a side surface, and a rear surface being opposite to the mounting surface;
• a front cover bonded with the mounting surface of the substrate and covering the mounting surface of the substrate;
• a metal plate bonded with the rear surface of the substrate;
• a side cover surrounding the side surface of the substrate;
• and
• a side end member covering at least one portion of the side cover and extending along the side surface of the substrate in a second direction that is orthogonal to the first direction,
• wherein the side end member comprises a body extending in the second direction, and a plurality of ribs extending from the body in the first direction and arranged at intervals along the second direction.
