Claim 3:
4. The display device according to claim 3, wherein
the reference luminance 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 luminance 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 luminance calculating unit configured to calculate the average luminance based on the degrees of degradation of the K pixel circuits; and
a reference luminance calculating unit configured to calculate the reference luminance by multiplying the average luminance by the adjustment factor.
