Abstract:
The present invention provides a layered body for organic electroluminescence which is excellent in the hardness, the transparency and the folding-durable performance.
The present invention is a layered body for organic electroluminescence in which an optical layered body is laminated on one surface of an organic electroluminescence layer and which is not cracked or fractured when a test in which the entire area of the layered body for organic electroluminescence is folded 180 degrees at 20 mm intervals is repeated 100,000 times.
