Display device and electronic device with a color filter

摘要

A novel display device capable of adjusting color purity is provided. A novel display device with improved adhesion of a color filter is provided. A novel display device capable of excellent reflective display is provided. The display device includes a transistor, a reflective electrode layer formed on the same surface as a source electrode layer or a drain electrode layer of the transistor, a first insulating layer over the reflective electrode layer, a coloring layer which is over the first insulating layer and overlaps with the reflective electrode layer, a second insulating layer over the coloring layer, and a pixel electrode layer over the second insulating layer. The coloring layer includes at least a first opening and a second opening. The pixel electrode layer is electrically connected to the transistor through the first opening. The second insulating layer is in contact with the first insulating layer in the second opening.
