Abstract: A display device including a peripheral circuit portion with high operation stability. The display device includes a first substrate and a second substrate. A first insulating layer is on a first plane of the first substrate, and a second insulating layer is on a first plane of the second substrate. An area of the first plane of the first substrate is the same as an area of the first plane of the second substrate. The first plane of the first substrate and the first plane of the second substrate face each other. A bonding layer is between the first insulating layer and the second insulating layer. A protection film is in contact with the first substrate, the first insulating layer, the bonding layer, the second insulating layer, and the second substrate.

A novel display panel in which reflected external light is reduced is provided. The present inventors have conceived a light-emitting device including a light-emitting module that emits light with a spectrum having a peak at one wavelength in a visible light region and an absorption layer that absorbs part of light with wavelengths shorter than the one wavelength and part of light with wavelengths longer than the one wavelength more easily than light with the one wavelength.

Abstract: A display device that is suitable for high definition and a method for manufacturing thereof are provided. The display device includes a reflective liquid crystal element. A liquid crystal layer has a first portion overlapping with a reflective electrode that reflects visible light and blocks ultraviolet light, and a second portion overlapping with a region between two adjacent reflective electrodes. The first portion contains a monomer and liquid crystal and the second portion contains a polymer obtained by polymerization of the monomer. In the second portion, the polymer constitutes the framework of a columnar partition wall which bonds a pair of substrates to each other. The partition wall can be formed in a self-aligned manner by using the reflective electrode as a light-blocking mask at the irradiation with light. The polymer is positioned to fit a depression portion of an insulating layer over which the reflective electrode is provided.
