Display device comprising display module, and method for manufacturing same

A display device comprising a display module array in which a plurality of display modules are arranged horizontally in a matrix form of M*N, wherein each of the plurality of display modules comprises:

• a substrate comprising a mounting surface on which a plurality of inorganic light-emitting devices are mounted, a side surface, and a rear surface opposite to the mounting surface;
• a front cover covering the mounting surface and extending to an outer area from the mounting surface;
• a metal plate mounted on the rear surface of the substrate;
• a side molding covering the side surface and positioned below the outer area from the mounting surface;
• and
• a grounding member being grounded to the metal plate and adhered to a lower surface of the side molding,
• wherein the side molding is injection-molded on the side surface of the substrate and is in contact with the side surface.

A method of manufacturing a display module, comprising:

• providing a substrate including a mounting surface on which a Thin Film Transistor (TFT) layer is formed, a side surface, and a rear surface being opposite to the mounting surface, wherein a wire is formed on the substrate;
• injection-molding a side molding on the side surface of the substrate;
• adhering an anisotropic conductive film onto the TFT layer;
• mounting a plurality of inorganic light-emitting devices on the mounting surface;
• adhering a front cover onto the mounting surface, the front cover extending to an outer area from the mounting surface;
• and
• cutting the front cover, the anisotropic conductive film, and the side molding simultaneously in a direction which the mounting surface faces.
