a substrate having a plurality of subpixel areas;

a plurality of first electrodes, each of the plurality of first electrodes disposed in a corresponding one of the plurality of subpixel areas;

a bank covering an end of each of the plurality of first electrodes, the bank defining an opening of each of the plurality of subpixel areas;

a disconnection portion disposed at boundary areas between the plurality of subpixel areas;

an undercut area in the disconnection portion, the undercut area formed under an end of the bank that extends past an end of a first electrode from the plurality of first electrodes;

a light emitting element layer including a first portion and a second portion, the first portion electrically connected to the first electrode and disposed on the first electrode, the bank, and the disconnection portion, and the second portion disposed in the disconnection portion but is not electrically connected to the first electrode due to the undercut area; and

a second electrode disposed on the light emitting element layer.
