Photo-alignment exposure device and photo-alignment exposure method

A photo-alignment exposure method by which each unit image area of a liquid crystal display is divided into a plurality of divided areas and an alignment material film of each of the divided areas is photo-aligned in mutually different directions, said method comprising:

• a first exposure process that independently proximity-exposes through a first mask a first divided area which is one of said divided areas, a second exposure process that independently proximity-exposes through a second mask a second divided area which is one of said divided areas and adjacent to said first divided area, and a third exposure process that exposes through a third mask an area on a side of said first divided area near a boundary between said first divided area and said second divided area, wherein
• in said third exposure process, exposure of an exposed surface is performed at a photo-irradiation angle same as that in said first exposure process, condensing element is disposed between a mask opening of said third mask and the exposed surface, and mask transmitted light is condensed on a side of said area on said first divided area near said boundary.
