    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.

    Abstract: A light-emitting display device includes a pixel defining layer with an opening that exposes a first electrode, a hole injection layer on the first electrode, a lyophilic pattern on the hole injection layer in the opening, a hole transport layer on the lyophilic pattern, a light-emitting layer on the hole transport layer, and a second electrode on the light-emitting layer. The lyophilic pattern includes a first part adjacent to a first sidewall of the opening and a second part adjacent to a second sidewall of the opening. A distance from a top surface of the hole injection layer to an edge of a top surface of the second part corresponds to a first height. A distance from the top surface of the hole injection layer to a top surface of the first part corresponds to a second height. The first height is lower than the second height.
