Method for manufacturing display device, display device, display module, and electronic device

Abstract

A high-resolution or high-definition display device is provided. The display device is manufactured by forming a plurality of first pixel electrodes aligned in a first direction and a plurality of second pixel electrodes aligned in the first direction so that the plurality of first pixel electrodes and the plurality of second pixel electrodes are aligned in a second direction; forming a first layer and a first sacrificial layer; processing the first layer and the first sacrificial layer to expose at least part of the second pixel electrodes; forming a second layer and a second sacrificial layer; processing the second layer and the second sacrificial layer to expose at least part of the first sacrificial layer; removing the first sacrificial layer and the second sacrificial layer; forming a third layer and a counter electrode; removing at least part of each of the third layer and the counter electrode included in a region between the adjacent pixel electrodes in a top view; forming a protective layer over the counter electrode; processing the protective layer to expose at least part of the counter electrode that overlaps with the pixel electrodes; and forming a conductive layer over the counter electrode and the protective layer.
