<p>Provided is a light exposure technology capable of stably forming images across an entire light exposure surface of a substrate, using a simple configuration. The light exposure device which exposes a flexible, belt-shaped substrate (S) comprises: two holding sections (20) formed using a light-transparent member, having transparent sections having flat surfaces, and comprising a first holding section (20a) and a second holding section (20b) that are capable of holding the substrate by using each flat surface; a first movement unit (50) that moves the two holding sections (20) in the approaching direction and the receding direction; a first light exposure unit (30) fixed in position on the first holding section (20a) side; a second light exposure unit (40) arranged on the second holding section (20b) side; and a second movement unit (60) that relatively moves the two holding sections and the two light exposure units, in a substrate-held state. The light exposure device maintains a set distance between each flat surface of the two holding sections (20) and the two light exposure units, moves the first and second holding sections (20a, 20b), feeds the substrate in the longitudinal direction, and simultaneously exposes both surfaces of the substrate via the transparent sections of the two holding sections (20).</p> |
