摘要:
A printing apparatus for manufacturing a spacer includes a printing plate and a printing roller. The printing plate has a plurality of receiving recesses formed thereon. The receiving recess has a generally elliptical shape. The receiving recesses are infiltrated with a plurality of beads. The printing roller transfers the beads onto its outer surface by rolling over the receiving recesses, and transfers the beads from its outer surface onto an external substrate. Thus, the spacers may maintain a distance between the first and second substrates stably, so that press characteristics may be enhanced and smear defects occurring when the display panel is pressed may be prevented.

A liquid crystal layer is formed by coating a liquid crystal material having a reciprocal (Z−1) of an Ohnesorge number in a range of 4≦Z−1≦14 by an ink-jet printing method. The reciprocal (Z−1) of the Ohnesorge number is a dimensionless number defined as Z−1=([σρL]1/2)/μ.

Exemplary embodiments of the present invention disclose a pattern transfer device and a pattern transfer method. The pattern transfer device may include a printing plate stage to load a printing plate having a pattern of a predetermined shape, and a substrate stage to load a substrate on which the pattern formed on the printing plate is to be printed. The pattern transfer device also includes a pressure unit configured with the printing plate stage to apply pressure to the printing plate, and a printing unit to transfer the pattern formed on the printing plate to the substrate.

A printing plate cleaning apparatus may include a cleaning chamber configured to receive a printing plate to be cleaned, a nozzle supporter in the cleaning chamber, and/or a unified nozzle unit that includes a cleaning nozzle unit and a rinsing nozzle unit unified as a body and attached to the nozzle supporter. The cleaning nozzle unit may include a cleaner nozzle configured to inject cleaner to the printing plate and/or a first suction nozzle suctioning waste. The rinsing nozzle unit may include a rinsing liquid nozzle configured to inject rinsing liquid to the printing plate and/or a second suction nozzle suctioning the waste. A printing plate cleaning apparatus may include the cleaning chamber, a cleaning nozzle unit in the cleaning chamber, and/or a rinsing nozzle unit in the cleaning chamber. The cleaning and rinsing nozzle units may be configured to move together with each other in the cleaning chamber.
