Abstract: A display device includes a substrate having a display area and a non-display area surrounding the display area. A drain electrode is disposed in the display area and is positioned adjacent to the non-display area. A light emitting element is disposed in the display area and is connected to the drain electrode. The light emitting element is disposed farther from the non-display area than the drain electrode. A plurality of first dams is disposed in the display area and is positioned between the drain electrode and the light emitting element. Each of the plurality of first dams are spaced apart from each other.

Abstract: An inkjet printing apparatus includes: a stage, which reciprocates in forward and reverse directions opposite to each other and has a target substrate disposed thereon; an inspection device including a film disposed outside the stage and a measurement unit which measures an inspection pattern provided on the film; and a head assembly, which moves along one direction crossing the forward direction and has a plurality of heads which supplies a liquid composition to the target substrate. The head assembly moves in the one direction to overlap the film and sprays the composition onto the film to form an inspection pattern.
