Abstract
In a sealing film in which a first inorganic film, an organic film, and a second inorganic film are layered in that order, a high-wettability region having a relatively high wettability with respect to droplets configured to become the organic film, and a low-wettability region having a relatively low wettability with respect to the droplets, are arranged in an alternating manner on an organic film side surface of the first inorganic film.
Claims15
A display device comprising:
- a base substrate in which a display region, in which an image is displayed, and a frame region located in the periphery of the display region are defined;
- a light emitting element provided in the display region of the base substrate;
- and
- a sealing film in which a first inorganic film, an organic film, and a second inorganic film are layered in that order, the sealing film being provided in the display region and the frame region, the sealing film covering the light emitting element,
- wherein a high-wettability region having a relatively high wettability with respect to droplets configured to become the organic film, and a low-wettability region having a relatively low wettability with respect to the droplets, are arranged in an alternating manner on an organic film side surface of the first inorganic film.

A method of manufacturing a display device, the method comprising:
- forming a light emitting element on a base substrate;
- and
- forming a sealing film covering the light emitting element,
- wherein the forming of the sealing film includes
- forming a first inorganic film covering the light emitting element,
- forming an organic film by applying an organic film upon the first inorganic film, and
- forming a second inorganic film covering the organic film, and
- in the forming of the first inorganic film, a high-wettability region having a relatively high wettability with respect to droplets configured to become the organic film, and a low-wettability region having a relatively low wettability with respect to the droplets, are formed on the first inorganic film alternately along a direction in which the organic film is applied in the forming of the organic film.
