Abstract

A display apparatus with high display quality is provided. A highly reliable display apparatus is provided. A display apparatus with low power consumption is provided. A display apparatus with a high resolution is provided. A display apparatus with high contrast is provided. The display apparatus includes a plurality of pixels over a first insulating layer. Each of the plurality of pixels includes a first conductive layer provided along an opening portion of the first insulating layer, a second insulating layer over the first conductive layer, an EL layer over the first conductive layer and the second insulating layer, and a common electrode over the EL layer. The second insulating layer is over and in contact with the first conductive layer and placed below the EL layer. The first conductive layers of adjacent pixels are separated by a third insulating layer containing an inorganic material and a fourth insulating layer containing an organic material. A side surface of the first conductive layer and a side surface of the EL layer each include a region in contact with the third insulating layer. The fourth insulating layer is over and in contact with the third insulating layer and placed below the common electrode.
