Claim 14:
15. The display device according to claim 14, wherein
the reference current setting circuit includes:
a parameter holding unit configured to hold, as parameters, a value, on a horizontal axis, of a critical point on a graph and a slope between adjacent critical points on the graph, so that the graph can be obtained, the graph having a value that the index value can take as the horizontal axis and having a value that an adjustment factor for calculating the reference current can take as a vertical axis, and the graph representing a correspondence between the index value and the adjustment factor;
an adjustment factor calculating unit configured to calculate the adjustment factor based on the parameters and the index value;
an average current calculating unit configured to calculate the average current based on the degrees of degradation of the K pixel circuits; and
a reference current calculating unit configured to calculate the reference current by multiplying the average current by the adjustment factor.
