An inkjet method of printing an alignment layer is presented. The method entails depositing drops of an alignment liquid on a substrate while moving a plurality of inkjet heads and/or the substrate relative to each other to form a first dropping line on the substrate. The method also entails rotating a printing stage on which the substrate is mounted, and depositing drops of the alignment liquid on the substrate after forming the fist dropping line to form a second dropping line. Since the printing stage is elevated and rotated, the drops of the alignment liquid are easily deposited in a grid pattern to decrease the space between adjacent drops. If desired, drops may be skipped to avoid depositing the alignment liquid multiple times on the same location on the substrate. With this method, the planarization time of the alignment layers is shortened.

Inkjet method and apparatus for printing an alignment layer

An apparatus for jetting an alignment agent includes a jetting head having a jetting hole, an alignment agent externally provided onto a substrate and a viscosity controlling part controlling a viscosity of the alignment agent stored in the jetting head to facilitate jetting of the alignment agent. The alignment agent is jetted to the substrate through the jetting hole. The apparatus improves the efficiency of jetting the alignment agent.
