Method of manufacturing surface-emitting panel having light-emitting pattern and surface-emitting panel having light-emitting pattern

摘要

An object of the present invention is to provide a method of manufacturing a surface emitting panel having a light emitting pattern with excellent gradation characteristics and a surface emitting panel having a light emitting pattern manufactured by the method. A method of manufacturing a surface emitting panel having a light emitting pattern of the present invention includes a step of irradiating an organic electroluminescence panel having at least one pair of electrodes with one or more organic functional layers to form a light emitting pattern at least Wherein in the step of forming the light emission pattern, a decrease in the light emission luminance of the light irradiated organic electroluminescence panel is equal to the light emission luminance before the light irradiation , The light emission pattern is formed by adjusting the light irradiation condition so that the voltage change amount required for setting the light emission pattern to 1.0 V or less.
