Abstract:
1. A method of forming a vertical alignment layer, comprising: disposing a substrate on a stage, the substrate comprising an alignment layer, wherein the alignment layer comprises first areas and second areas alternately arranged in a first direction; disposing a mask over the substrate, the mask comprising light blocking parts that block light and light transmitting parts through which light passes and that correspond to the first areas; disposing an exposure apparatus over the mask; providing, from the exposure apparatus, first light pulses to the first areas while the substrate moves in the first direction to form a pretilt angle in the first areas; rotating the stage so that the light transmitting parts correspond to the second areas; and providing, from the exposure apparatus, second light pulses to the second areas while the substrate moves in the first direction to form a pretilt angle in the second areas, wherein the pretilt angle formed in the first areas is different from the pretilt angle formed in the second areas, wherein the first and second areas extend in a second direction substantially perpendicular to the first direction, the first areas are light aligned in the first direction, and the second areas are light aligned in a third direction opposite to the first direction.
