Abstract:
1. An exposure apparatus, comprising: a conveying device that conveys a subject to be exposed in one direction; a photomask on which a plurality of mask patterns are formed, wherein two mask pattern groups formed by two types of mask patterns requiring different resolutions are formed on a light shielding film formed on one surface of a transparent substrate in front and back of the conveying direction of the subject to be exposed, wherein micro-lenses that reduce and project one mask pattern requiring a high resolution among the two types of mask patterns requiring different resolutions onto the subject to be exposed are formed on the other surface of the transparent substrate in a position corresponding to the one mask pattern requiring a high resolution, and wherein the photomask is disposed so that the micro-lenses face the subject to be exposed; and a light source that intermittently irradiates light to the photomask to thereby form an exposure pattern on the subject to be exposed corresponding to the plurality of mask patterns formed on the photomask, while conveying the subject to be exposed in one direction.
