Abstract
An ultraviolet light monitoring system includes first and second electrodes, an evaluation subject film and a power source. The first and second electrodes are opposingly disposed and attract holes which are generated in accordance with irradiation of ultraviolet light. The evaluation subject film is formed in a vicinity of the first and second electrodes, and is a subject of evaluation of damage caused by the irradiation of ultraviolet light. The power source, at times of monitoring of the ultraviolet light, applies a predetermined bias to a series path formed by the first electrode, a gap between the first and second electrodes, and the second electrode.
