摘要： A reference luminescence amount-acquiring unit of a display device obtains reference brightness corresponding to a BL drive value detected by a drive value-detecting unit and a temperature detected by a temperature-detecting unit. A deterioration-detecting unit calculates an initial status value based on a ratio of reference brightness obtained based on a temperature and a BL drive value in an initial status and brightness in the initial status detected by a luminescence amount-detecting unit, and stores the initial status value. The deterioration-detecting unit further calculates a current status value based on a ratio of reference brightness obtained based on a current temperature and a current BL drive value and current brightness detected by the luminescence amount-detecting unit, compares the initial status value with the current status value, and determines whether calibration is required. When calibration is determined to be required, a warning screen display unit causes performance deterioration to be displayed on a display unit.
