Abstract
A maskless exposure device includes a stage on which a substrate is disposed, an optical head, and an optical source part. The optical head irradiates light to the substrate. The light source part provides the optical head with a light. The optical head irradiates the light, according to an average-focus distance, to the substrate. The average-focus distance is determined by averaging best-focus distances for a plurality of regions of the substrate, respectively.
