Abstract: A light exposure device is provided. The light exposure device includes a light source, a light modulation part, and a projection optical part. The light modulation part modulates the light based on a predetermined exposure pattern. The projection optical part projects the light from the light modulation part onto a substrate. The projection optical part includes a first optical part, a hole arrangement part, and a second optical part. The first optical part receives the light from the light modulation part. The first optical part includes a plurality of first lenses. The hole arrangement part emits the light from the first optical part. The second optical part emits the light from the hole arrangement part onto the substrate. The second optical part includes a plurality of second lenses. At least one of the first lenses and the second lenses is a transreflective lens.

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.
