Abstract: An object of the present invention is to provide such a sealing structure that a material to be a deterioration factor such as water or oxygen is prevented from entering from external and sufficient reliability is obtained in a display using an organic or inorganic electroluminescent element. In view of the above object, focusing on permeability of an interlayer insulating film, deterioration of an electroluminescent element is suppressed and sufficient reliability is obtained by preventing water entry from an interlayer insulating film according to the present invention.
