Printing apparatus and method of forming an organic light emitting layer

摘要

A printing apparatus includes a printing mask, which is disposed between a substrate having a display area and a non-display area surrounding the display area. The apparatus further includes a nozzle discharging an organic light emitting liquid onto the substrate. The printing mask includes a mask open part and a mask cover part. The mask open part exposes the display area, and the mask cover part surrounds the mask open part and covers the non-display area. The apparatus can be used to form an organic emitting layer on the substrate.
