Abstract

A display apparatus-including a first pixel, a second pixel adjacent to the first pixel, a first insulating layer, and a second insulating layer over the first insulating layer is provided. The first pixel includes a first pixel electrode, a first EL layer covering the first pixel electrode, a third insulating layer over the first EL layer, and a common electrode over the first EL layer. The common electrode is in contact with part of the top surface of the first EL layer. The first EL layer contains a first organic compound. The amount of an organic compound that includes an oxide of the first organic compound or a partial structure of the first organic compound and is contained in the first EL layer is greater than 0 and less than or equal to 1/10 of an amount of the first organic compound contained in the first EL layer.
