Title: METHOD FOR FABRICATION OF PLANAR LIGHT EMITTING PANEL HAVING LIGHT EMISSION PATTERN AND PLANAR LIGHT EMITTING PANEL HAVING LIGHT EMISSION PATTERN
Abstract:
A problem to be solved by the present invention is to provide a method for fabrication of a planar light emitting panel having a light emission pattern with superior gradation characteristics, and a planar light emitting panel having the light emission pattern which is fabricated by the method for fabrication. This method for fabrication of a planar light emitting panel having a light emission pattern comprises at least a step of projecting light upon an organic electroluminescence panel comprising at least one or more organic function layers between a pair of electrodes and forming a light emission pattern thereupon. In the light emission pattern forming step, light projection conditions are adjusted and the light emission pattern formed such that the degree of voltage change necessary for a decline in light emission brightness of the organic electroluminescence panel whereupon the light is projected to be the same as the light emission brightness prior to the projection of the light thereupon is less than or equal to 1.0V.
