PROBLEM TO BE SOLVED: To prevent the life of a light-emitting element from being reduced by increased temperature of a control section.SOLUTION: A light emission section 100 includes, for example, a light-emitting element such as an organic EL and an LED. A control section 200 controls power supplied to the light emission section 100. In particular, the control section 200 sets an upper limit of control power which is a power controlled by the control section 200 on the basis of an accumulated light emission time of the light emission section 100, and controls the control power on the basis of the upper limit that is set. For example, the control section 200 increases the upper limit of the control power as the accumulated light emission time of the light emission section 100 is longer. |
