Abstract

A highly reliable display apparatus is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, and an inorganic insulating layer. The first light-emitting device includes a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer. The second light-emitting device includes a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer. The inorganic insulating layer covers side surfaces of the first pixel electrode, the second pixel electrode, the first light-emitting layer, and the second light-emitting layer. The hydrogen concentration and the carbon concentration in the inorganic insulating layer are each preferably sufficiently low.
