Display device

A display device comprising:

• a first electrode;
• a second electrode spaced apart from the first electrode;
• a lower insulating layer on the first electrode and the second electrode;
• a plurality of light emitting elements on the first electrode and the second electrode on the lower insulating layer and electrically connected to the first electrode and the second electrode;
• a bank layer extending around a region at where the light emitting elements are arranged, the bank layer being on the lower insulating layer and having a plurality of trench portions that are partially depressed portions of a top surface of the bank layer;
• a first insulating layer on the light emitting elements and the bank layer, the first insulating layer having a plurality of opening holes that do not overlap the first electrode and the second electrode;
• a first connection electrode on the first electrode and in contact with the light emitting element;
• and
• a second connection electrode on the second electrode and in contact with the light emitting element,
• wherein the plurality of opening holes comprises an opening which overlaps one of the trench portions.
