Abstract: An organic semiconductor device that can achieve high resolution and favorable reliability is provided. The organic semiconductor device is one of a plurality of light-emitting devices formed over an insulating layer, which includes a first electrode, a second electrode, and an organic compound layer. The organic compound layer is positioned between the first electrode and the second electrode. The organic compound layer includes a layer containing a first compound. When differential scanning calorimetry is performed on the first compound in such a manner that a cooling step is performed from the state in which the first compound is melted in a first heating step and a second heating step is successively performed, an exothermic peak is not observed in the cooling step and an exothermic peak and a melting point peak are not observed in the second heating step.

Abstract: Provided is a novel light adjustment program that can make a human feel at ease. Provided is the light adjustment program that includes the steps of obtaining basic data having 1/f fluctuation characteristics; generating first smoothed data and second smoothed data by performing moving average processing with different periods on the basic data having 1/f fluctuation characteristics; generating light adjustment data by subjecting the first smoothed data and the second smoothed data to arithmetic processing; and changing luminance of a light-emitting device in time series in accordance with the light adjustment data.
