Abstract:
1. An exposure device comprising: a light source that emits light beams for illumination; a spatial light modulator in which a plurality of pixel portions whose respective light modulation states change in correspondence to control signals are two-dimensionally arranged and which modulates, per pixel portion, the light beams that are incident at the plurality of pixel portions from the light source; a microlens array in which a plurality of microlenses are two-dimensionally arranged at a pitch corresponding to the plurality of pixel portions and which condenses, per microlens, the light beams modulated by the pixel portions; and a light-blocking film disposed on a light-emitting surface of the microlens array, the light-blocking film having a plurality of micro-openings which are two-dimensionally arranged at a pitch corresponding to condensing positions of the plurality of microlenses, wherein a photosensitive material is exposed by evanescent light leaking out from the plurality of micro-openings.
