Claim 7:
8. The display device according to claim 7, 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 base reference luminance by multiplying the average luminance by the adjustment factor, and calculate the reference luminance for each color based on the base reference luminance.
