Display apparatus and method of detecting crack in display apparatus

A display apparatus comprising:

• a substrate including a display area and a non-display area outside the display area;
• a plurality of drive circuits disposed in a matrix form on the substrate in the display area;
• a plurality of insulation layers disposed on the plurality of drive circuits;
• a plurality of banks disposed on the plurality of insulation layers in the display area;
• a plurality of micro-light emitting didoes (micro-LEDs) disposed on the plurality of banks;
• a plurality of first crack detection lines disposed on the plurality of drive circuits in the display area and extending in a first direction;
• and
• a plurality of second crack detection lines disposed on the plurality of drive circuits in the display area and extending in a second direction intersecting the first direction,
• wherein the plurality of first crack detection lines electrically connects the plurality of drive circuits disposed in the first direction, and
• wherein the plurality of second crack detection lines electrically connects the plurality of drive circuits disposed in the second direction.
