PROBLEM TO BE SOLVED: To provide a characteristic measurement method of an electric element which is a factor of variation of luminance among pixels.SOLUTION: A matrix device comprises components (pixels) arranged in a matrix state, and a wiring. The respective components can supply current with an electric element included in the respective components, to the wiring. In N components capable of supplying current to the wiring, respective orientations of current of the N components are individually set, and current flowing on the wiring is measured N times. The orientation of current flowing on the electric element can be changed. In each of N times measurement, a combination of the current orientations of the N components is different. Based on the obtained current by N times measurement, and the combination of the current orientation of the N times measurement, magnitude of current flowing respective electric element is calculated.SELECTED DRAWING: Figure 3 |
