Method for manufacturing display device

Abstract

A display device that can easily achieve higher resolution is provided. A display device having high display quality and high resolution is provided. A display device with high contrast is provided. A highly reliable display device is provided. The display device is manufactured in the following manner: a first pixel electrode and a second pixel electrode are formed over a substrate; an insulating layer is formed between the first pixel electrode and the second pixel electrode; a conductive film is formed over the first pixel electrode, the second pixel electrode, and the insulating layer; a first side surface of the conductive film is formed by removing a portion of the conductive film overlapping with the first pixel electrode; a first organic compound layer is formed over the first pixel electrode and the conductive film; a sacrificial layer is formed over the first organic compound layer; a second side surface of the conductive film is formed by removing a portion of the conductive film overlapping with the second pixel electrode; a second organic compound layer is formed over the sacrificial layer and the second pixel electrode; the sacrificial layer is removed; and an upper electrode is formed over the first organic compound layer and the second organic compound layer to be in contact with the first side surface and the second side surface.
