Display apparatus using semi-conductor light-emitting device

A display apparatus, comprising:

• a display unit;
• a plurality of semiconductor light emitting elements having at least a first conductive electrode to form individual pixels of the display unit;
• an adhesive layer disposed between adjacent semiconductor light emitting elements;
• a thin-film transistor having a gate region disposed closer to an upper surface of the display unit than a source region and a drain region;
• a via hole formed in the adhesive layer;
• a via hole electrode extending in the via hole and electrically connecting the at least one conductive electrode of a corresponding semiconductor light emitting element and a source-drain electrode of the thin-film transistor;
• and
• a connection electrode connecting the via hole electrode to the first conductive electrode,
• wherein the via hole electrode extends in the via hole and to a lower surface of the adhesive layer, and
• wherein the connection electrode is disposed on the lower surface of the adhesive layer and is not disposed within the via hole.
