A print head unit (10) for manufacturing a patterned layer on a substrate is provided. The print head unit includes a first print head (12a), a second print head (12b), a third print head (12c), and a print head frame (11). The print head unit further includes parallelism adjusting means and position adjusting means. The parallelism adjusting means configured for rotationally moving at least one of the first print head and the third print head relative to the second print head so as to adjust parallelism between the first nozzle line, the second nozzle line, and the third nozzle line. The position adjusting means is configured for linearly moving at least one of the first print head and the third print head in the nozzle line direction.
