Display module and display device

A display device comprising:

• a plurality of display modules comprising a plurality of pixels arranged two-dimensionally;
• and
• a frame supporting the plurality of display modules,
• wherein each of the plurality of display modules comprises:
• a first substrate;
• a plurality of inorganic light-emitting devices disposed on an upper surface of the first substrate;
• a plurality of micro pixel controllers disposed on a lower surface of the first substrate;
• and
• a driver integrated chip (IC) configured to transfer a driving signal to the plurality of micro pixel controllers,
• wherein each of the plurality of pixels comprises two or more inorganic light-emitting devices among the plurality of inorganic light-emitting devices,
• wherein each of the plurality of micro pixel controllers controls two or more pixels among the plurality of pixels, and
• wherein each of the plurality of micro pixel controllers has a length of a shorter side that is longer than a distance between adjacent inorganic light-emitting devices in different pixels among the pixels controlled by the micro pixel controller.
