    Patent number: 9063378
    Abstract: In a photo alignment method, a substrate and a mask are aligned so that the substrate is spaced apart from the mask by a predetermined gap. An organic layer is formed on the substrate. The mask has a transmission portion and a light blocking portion. Light is irradiated through the mask in a direction substantially parallel with an interface between the transmission portion and the light blocking portion of the mask. Polymer chains are formed on an upper portion of the organic layer. The polymer chains are aligned in an alignment direction toward an incident direction of the light. Locations of the substrate and the mask are sensed in real time. The mask is transported to a predetermined location with respect to the substrate based on the sensed locations of the substrate and the mask.
