PHOTO ALIGNMENT-PHOTO CURABLE COMPOSITION CAPABLE OF FORMING A SPACER AND AN ALIGNMENT LAYER AT THE SAME TIME, A FORMATION METHOD OF THE SPACER AND THE ALIGNMENT LAYER, AND THE SPACER AND THE ALIGNMENT LAYER

摘要

PURPOSE: A photo alignment-photo curable composition, a formation method of a spacer and an alignment layer using thereof, and the spacer and the alignment layer are provided to simplify the manufacturing process, and to reduce the manufacturing cost.;CONSTITUTION: A photo alignment-photo curable composition contains a photo alignment polymer including a photo-reactive group showing the photo anisotropy, and an oligomer including a photo polymerizable reactor. 5~10wt% of oligomer is included to the total composition. A formation method of a spacer and an alignment layer at the same time using the composition comprises the following steps: forming a layer of the photo alignment-photo curable composition on a substrate; transferring the shape of the spacer and the alignment layer using a PDMS stamp; and curing the alignment layer including the shape of the spacer by irradiating polarized light ultraviolet rays.;COPYRIGHT KIPO 2010
