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.
