Display apparatus
View Patent ↗The present invention provides a display apparatus in which destruction of an insulating film by water or water vapor and generation of air bubbles in the display apparatus can be suppressed. The display apparatus includes a display element having a display layer together with a pixel electrode and an opposite electrode, an insulating film in contact with an under face of the pixel electrode and a metal-containing film that contains a metal element, covers an end face of the insulating film, and covers a part of a top face and a part of an under face which continue to the end face of the insulating film.
1. A display apparatus comprising:
a display element having a display layer together with a pixel electrode and an opposite electrode;
an insulating film in contact with an under face of the pixel electrode; and
a metal-containing film that contains a metal element, covers an end face of the insulating film, and covers a part of a top face and a part of an under face which continue to the end face of the insulating film,
wherein,
the insulating film is provided between the pixel electrode and the opposite electrode and is in contact with the under face of the pixel electrode and the top face of the opposite electrode.
2. The display apparatus according to claim 1 , wherein:
the display element is disposed in a display region on a substrate,
a seal layer is provided on the outside of the display region, and
the end face of the insulating film is positioned on the inside of the seal layer.
3. The display apparatus according to claim 2 , wherein:
a peripheral wiring is provided between the display region and the seal layer, and
the peripheral wiring serves as a part covering the part of the under face of the insulating film, of the metal-containing film.
4. The display apparatus according to claim 1 , wherein the metal-containing film is made of at least one element selected from the group consisting of indium, tin, zinc, aluminum, molybdenum, titanium, tungsten, chromium, tantalum, and silver.
5. A display apparatus comprising:
a display element having a display layer together with a pixel electrode and an opposite electrode;
an insulating film in contact with an under face of the pixel electrode; and
a metal-containing film that contains a metal element, covers an end face of the insulating film, and covers a part of a top face and a part of an under face which continue to the end face of the insulating film,
wherein,
the display element is disposed in a display region on a substrate,
a seal layer is provided on the outside of the display region,
the end face of the insulating film is positioned on the inside of the seal layer,
the end face of the insulating film lies on the inside of the end face of the opposite electrode, and
the opposite electrode serves as a part covering the part of the under face of the insulating film, of the metal-containing film.
6. The display apparatus according to claim 5 , wherein:
a film is provided in the layer of the pixel electrode, and
the film serves as a part covering the end face and the part of the top face of the insulating film, of the metal-containing film.
7. The display apparatus according to claim 5 , wherein:
a peripheral wiring is provided between the display region and the seal layer, and
the peripheral wiring serves as a part covering the end face and the part of the top face of the insulating film, of the metal-containing film.
8. The display apparatus according to claim 5 , wherein:
a peripheral light shield layer is provided between the display region and the seal layer, and
the peripheral light shield layer serves as a part covering the end face of the insulating film and the part of the top face of the insulating film, of the metal-containing film.
9. A display apparatus comprising:
a display element having a display layer together with a pixel electrode and an opposite electrode;
an insulating film in contact with an under face of the pixel electrode; and
a metal-containing film that contains a metal element, covers an end face of the insulating film, and covers a part of a top face and a part of an under face which continue to the end face of the insulating film,
wherein,
a part covering each of the top and under faces of the insulating film, of the metal-containing film has a length of 100 nm or more from the end face of the insulating film.
