    Abstract: A display module includes a base substrate including an upper surface where a display area and a non-display area are defined, a lower surface, and a plurality of side surfaces, a circuit element layer including a planarization layer, a pixel defining layer defining an opening portion that overlaps the display area and exposes a portion of the planarization layer, a display element layer including a first electrode disposed on the planarization layer exposed by the opening part, a light emitting layer, and a second electrode, and a sealing layer disposed on the display element layer. A dam hole is defined, which is adjacent to an edge where two side surfaces of the side surfaces are connected in a plan view of the base substrate, overlaps the non-display area, and penetrates at least one of the planarization layer and the pixel defining layer.

    Abstract: A method of inspecting light emitting elements includes disposing a first electrode and a second electrode on a substrate. A solution including a plurality of light emitting elements is applied on the first electrode and the second electrode. A first voltage is applied across the first electrode and the second electrode so as to cause the plurality of light emitting elements to emit light. The light emitted from the plurality of light emitting elements is photographed and first image data is generated therefrom. A density of the plurality of light emitting elements is determined using the first image data.
