    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.
