Abstract: A display device comprises a display area and a non-display area, sub-pixels in the display area, each sub-pixel including a first electrode and a second electrode extended in a first direction and light-emitting elements disposed on the first electrode and the second electrode, sub-lines disposed in the non-display area and extended in a second direction, and conductive patterns extended in the first direction, each conductive pattern being connected to at least one of the plurality of sub-lines. The sub-lines comprise first, second, and third sub-lines sequentially disposed from the first sub-line toward the display area. The conductive patterns are disposed in at least one of the sub-pixels closest to the sub-lines. The conductive patterns comprise a first conductive pattern connected to the first sub-line, second conductive patterns connected to the second sub-line, and a third conductive pattern connected to the third sub-line.

Abstract: An Inkjet printer includes a substrate on a stage. A print head unit is positioned above the stage and discharges an ink on the substrate. The print head unit includes a manifold for guiding movement of the ink in a first direction therein. A head block is under the manifold and includes a plurality of channels connected to the manifold and piezoelectric elements adjacent to the channels to discharge the ink through the channels. A nozzle unit is under the head block and includes nozzles corresponding to the channels. A dispersion plate is between the manifold and the head block and disperses the ink in a second direction intersecting the first direction to supply the ink to the head block. Resistance plates are between the dispersion plate and the head block, are formed parallel substantially to the second direction, and prevent the ink from flowing in the first direction.
