Exposure apparatus for photoalignment process and method for manufacturing liquid crystal display

An exposure apparatus for a photo alignment process, the exposure apparatus comprising:

• a first photomask including a plurality of transmission parts;
• and
• a second photomask including a plurality of transmission parts,
• wherein the first photomask and the second photomask partially overlap each other such that each of the first photomask and the second photomask includes an overlapping region and a non-overlapping region,
• each of the first photomask and the second photomask include a first portion and a second portion, and irradiation regions corresponding to the first portion are different from irradiation regions corresponding to the second portion,
• an irradiation direction of lights passing through a transmission part in the first portion is different from an irradiation direction of lights passing through a transmission part in the second portion, and
• a shape or an arrangement of the transmission parts in the overlapping region of the first photomask or the second photomask is different from a shape or an arrangement of the transmission parts in the non-overlapping region of the first photomask or the second photomask.

An exposure apparatus for a photoalignment process, the exposure apparatus comprising:

• a first photomask including a plurality of transmission parts arranged in a first direction;
• and
• a second photomask including a plurality of transmission parts arranged in the first direction,
• wherein the first photomask and the second photomask partially overlap each other such that each of the first photomask and the second photomask includes an overlapping region and a non-overlapping region,
• a transmission part of at least one of the first photomask and the second photomask has a shape that is asymmetric in a direction parallel to the first direction, and
• a shape or an arrangement of the transmission parts in the overlapping region of the first photomask or the second photomask is different a shape or an arrangement of the transmission parts in the non-overlapping region of the first photomask or the second photomask.
