Classification: CPC B  G  H | IPC G

Claim 9:
10. An exposure device configured to expose a substrate while moving the substrate in a first direction, the exposure device comprising:
a first light source;
a first spatial light modulator and a second spatial light modulator that are arranged in a second direction crossing the first direction and into which light from the first light source enters;
a data transmission unit configured to transmit first pattern data to the first spatial light modulator and second pattern data to the second spatial light modulator;
a first projection optical system configured to project an image formed on the first spatial light modulator based on the first pattern data to the substrate;
a second projection optical system configured to project an image formed on the second spatial light modulator based on the second pattern data to the substrate; and
an optical path switching machine configured to switch an optical path of the light from the first light source so as to sequentially guide the light to the first spatial light modulator and the second spatial light modulator,
wherein the data transmission unit is configured (i) to divide device pattern data into the first pattern data and the second pattern data and (ii) relatively shift positions of the first pattern data and the second pattern data related to the first direction.
