Abstract
Provided is a method for manufacturing a display device. The method includes: forming a first electrode; forming an insulating film covering an edge portion of the first electrode; forming an EL layer over the first electrode and the insulating film; forming a second electrode over the EL layer; forming, over the second electrode, a first layer including an inorganic compound; forming, over the first layer, a second layer including an organic compound so as to overlap with the insulating film and the EL layer; thinning the second layer so that the first layer is exposed in a region overlapping with the insulating film; and forming, over the second layer, a third layer including an inorganic compound.
Claims14
A display device comprising:
- a first sub-pixel and a second sub-pixel adjacent to each other and each including a light-emitting element which comprises:
- a first electrode;
- a second electrode;
- and
- an EL layer sandwiched between the first electrode and the second electrode;
- an insulating film located between the first sub-pixel and the second sub-pixel and overlapping with the first electrodes of the first sub-pixel and the second sub-pixel;
- a first layer overlapping with the light-emitting elements of the first sub-pixel and the second sub-pixel and including an inorganic compound as a main component;
- a second layer over the first layer, the second layer including an organic compound as a main component;
- and
- a third layer over the second layer, the third layer including an inorganic compound as a main component,
- wherein the second layer is divided between the first sub-pixel and the second sub-pixel.
A display device comprising:
- a light-emitting element comprising:
- a first electrode;
- an EL layer over the first electrode;
- and
- a second electrode over the EL layer;
- an insulating film underneath the EL layer, the insulating film covering an edge portion of the first electrode and having an opening portion overlapping with the first electrode;
- a first layer over the light-emitting element, the first layer including an inorganic compound as a main component;
- a second layer over the first layer, the second layer including an organic compound as a main component;
- and
- a third layer over the second layer, the third layer including an inorganic compound as a main component,
- wherein the first layer and the third layer are in contact with each other in a region overlapping with the insulating film, and
- wherein a top surface of the second layer is flat in a region overlapping with the opening portion.
