Abstract:
Disclosed is a display device (1) which is provided with: a plurality of light sources (a1-an), which emit light corresponding to emission currents, and which have illuminating regions illuminated by the light emission overlap each other; and a managing unit (11), which stores, as use history, the use quantities of the emission currents of the plurality of light sources (a1-an) by associating the use quantities with the use periods, respectively, and manages the average value of the emission currents and the lifetime. Therefore, even in the display device (1) having the light sources (a1-an) advantageously disposed with respect to manufacture cost, power consumption is reduced and the lifetime is increased.
