Mother substrate including display cells, and method for fabricating display device

A mother substrate comprising:

• a support substrate;
• a first organic film on the support substrate;
• a first inorganic film arranged on the first organic film and covering an edge of the first organic film;
• a second organic film on the first inorganic film;
• a second inorganic film arranged on the second organic film and covering an edge of the second organic film;
• a plurality of display cells on the second inorganic film;
• and
• an encapsulation cover layer on a first inorganic encapsulation area where the first inorganic film and the second inorganic film contact each other,
• wherein the encapsulation cover layer comprises a plurality of encapsulation cover layers spaced from one another, and
• wherein the plurality of encapsulation cover layers is arranged more inward than an edge of the first inorganic film and an edge of the second inorganic film on the support substrate or the mother substrate.

A method comprising:

• sequentially arranging a first organic film, a first inorganic film, a second organic film, and a second inorganic film on a support substrate;
• arranging a plurality of display cells and an encapsulation cover layer on the second inorganic film;
• separating the support substrate from the first organic film;
• and
• cutting the plurality of display cells,
• wherein the arranging of the plurality of display cells and the encapsulation cover layer on the second inorganic film comprises:
• arranging the encapsulation cover layer on the first inorganic encapsulation area where the first inorganic film not covered by the second organic film and the second inorganic film contact each other,
• wherein the encapsulation cover layer is more inward than an edge of the first organic film, and
• wherein the method is a method for fabricating a display device.
