Abstract
A photo-alignment exposure device that includes a first mask and a first exposure device that independently proximity-exposes a first divided area, a second mask and a second exposure device that independently proximity-exposes a second divided area adjacent to the first divided area, and a third mask and a third exposure device that exposes an area on a side of the first divided area near a boundary between the first divided area and the second divided area. The third exposure device is provided with a photo-irradiation angle same as that of the first exposure device or the second exposure device with respect to an exposed surface. A condensing element that condenses the mask transmitted light on the area on a side of the first divided area near the boundary is provided between the mask opening of the third mask and the exposed surface.
