<p>A transparent substrate capable of improving the light extracting efficiency of an organic electroluminescence element, and a practical organic electroluminescence element using this. An organic electroluminescence element-use transparent substrate characterized by providing on at least one surface of the transparent substrate a region that disturbs the reflection/refraction angle of light emitted from a light emitting element, and an organic electroluminescence element having the substrate.</p> |
