The organic-inorganic hybrid layer contains silicon, carbon and nitrogen. The first inorganic encapsulation layer, the second inorganic encapsulation layer and the third inorganic encapsulation layer each contains silicon and nitrogen. An atomic ratio of nitrogen to silicon (N/Si ratio) in the organic-inorganic hybrid layer is greater than an atomic ratio of nitrogen to silicon (N/Si ratio) in the first inorganic encapsulation layer and an atomic ratio of nitrogen to silicon (N/Si ratio) in the third inorganic encapsulation layer.
