Abstract:
1. A display device comprising: a substrate; electroluminescence elements which are mounted on the substrate; and a protective film of n layers which is formed by sequentially laminating protective films of n layers ranging from the first protective film to the n-th protective film (n being a natural number of 3 or more) over the electroluminescence elements, wherein at least the n-th protective film out of the protective films of n layers is formed of a synthetic resin film with chemical reaction curing, and wherein hardness of the protective film of n layers which cover the electroluminescence element is gradually increased from the electroluminescence element side such that the hardness satisfies a following inequality: the hardness of the first protective film<the hardness of the second protective film< . . . <the hardness of the n-th protective film.
