Abstract: A decomposition reaction of an electrolyte solution and the like caused as a side reaction of charge and discharge is minimized in repeated charge and discharge of a lithium ion battery or a lithium ion capacitor, and thus the lithium ion battery or the lithium ion capacitor can have long-term cycle performance. A negative electrode for a power storage device includes a negative electrode current collector and a negative electrode active material layer which includes a plurality of particles of a negative electrode active material. Each of the particles of the negative electrode active material has an inorganic compound film containing a first inorganic compound on part of its surface. The negative electrode active material layer has a film in contact with an exposed part of the negative electrode active material and part of the inorganic compound film. The film contains an organic compound and a second inorganic compound.

Abstract: A display apparatus with extremely high resolution is provided. A display apparatus with high display quality is provided. The display apparatus includes a first light-emitting element and a second light-emitting element over a first insulating layer, a second insulating layer, and a third insulating layer. The first light-emitting element includes a first pixel electrode and a first organic layer. The second light-emitting element includes a second pixel electrode and a second organic layer. The first insulating layer includes a groove-like region provided along a side of the first pixel electrode in a plan view. The groove-like region includes a first region overlapping with the first pixel electrode and a second region overlapping with the second pixel electrode. The first region and the second region each have a width greater than or equal to 20 nm and less than or equal to 500 nm. The second insulating layer includes a region in contact with a top surface of the first organic layer, a region in contact with a side surface of the first organic layer, and a region located below the first pixel electrode. The third insulating layer includes a region in contact with a top surface of the second organic layer, a region in contact with a side surface of the second organic layer, and a region located below the second pixel electrode.
