Abstract
An organic EL display device is provided with an eaves body that includes a protruding portion outside a display region on a TFT substrate, along an edge portion on which a first inorganic layer and a second inorganic layer of a sealing film are provided. The first inorganic layer and the second inorganic layer cover the protruding portion and are split apart below the protruding portion facing a wall surface of the eaves body.
Claims21
A display device comprising:
- a support body;
- a plurality of light emitting elements provided on the support body;
- and
- a sealing film configured to seal the plurality of light emitting elements,
- wherein the sealing film includes at least an inorganic layer,
- the inorganic layer covers at least part of an edge portion of the support body in a plan view,
- an eaves body including an eaves portion is provided outside a display region of the support body in which the plurality of light emitting elements are disposed and provided along the edge portion on which the inorganic layer is provided in a plan view,
- the eaves portion is provided protruding above the support body in a cross-sectional view, on at least one of edge portions of the eaves body along the edge portion of the support body, and
- the inorganic layer covers the eaves portion and is split apart below the eaves portion facing a wall surface of the eaves body.
A method for manufacturing a display device including a support body, a plurality of light emitting elements provided on the support body, and a sealing film configured to seal the plurality of light emitting elements, the method comprising:
- forming the plurality of light emitting elements on a mother substrate configuring at least part of the support body such that a plurality of display regions, on which the plurality of light emitting elements are disposed, are formed corresponding to each display device;
- forming an eaves body including an eaves portion along a scheduled division line on which the mother substrate is divided and singulated into individual display devices in a plan view, the eaves portion being provided on at least one edge portion of edge portions along the scheduled division line and protruding in an in-plan direction above the support body in a cross-sectional view;
- forming the sealing film;
- and
- dividing the mother substrate, on which the sealing film is formed, along the scheduled division line around each of the plurality of display regions,
- wherein the forming the sealing film includes forming an inorganic layer, and
- in the forming an inorganic layer, the inorganic layer is formed such that the inorganic layer covers the eaves portion and covers the scheduled division line along the edge portion of the eaves body in a plan view, and the inorganic layer is split apart below the eaves portion facing a wall surface of the eaves body.
