Abstract:
1. A manufacturing method for an electroluminescent element comprising: first manufacturing of an electroluminescent element (a first manufacturing step) that manufactures an electroluminescent element in which, on a substrate, a first electroconductive layer, a dielectric layer with a plurality of contact holes passing through in a direction orthogonal to the substrate formed therein, a second electroconductive layer that is electrically connected to the first electroconductive layer inside the contact holes and fills the contact holes, a light-emitting layer and a third electroconductive layer are successively laminated; a temperature distribution measurement step that applies a voltage to the first electroconductive layer and the third electroconductive layer of the electroluminescent element manufactured in the first manufacturing step to cause the light-emitting layer to emit light, and measures temperature distribution of the electroluminescent element to obtain temperature unevenness information of the electroluminescent element; and second manufacturing of an electroluminescent element (a second manufacturing step) that adjusts a density of the plurality of contact holes passing through the dielectric layer based on the temperature unevenness information, to thereby reduce temperature unevenness of the electroluminescent element.
