Abstract: A display device divided into a display region and a non-display region adjacent to the display region includes a base layer, a light-emitting element layer, a first inorganic encapsulation film, an organic encapsulation film, a second inorganic encapsulation film, and a hydrophobic coating layer. The second inorganic encapsulation film which covers the organic encapsulation film, and the hydrophobic coating layer which covers an edge region of the first inorganic encapsulation film and is disposed on the first inorganic encapsulation film. The edge region may be defined as a region in which the first inorganic encapsulation film and the second inorganic encapsulation film do not overlap, and in a direction perpendicular to a thickness direction, the organic encapsulation film and the hydrophobic coating layer are spaced apart from each other with the second inorganic encapsulation film therebetween.
