Abstract: A thin display device, a lightweight display device, or a bendable display device is provided. The display device can be fabricated by a method including a first step of forming a first electrode and a second electrode over a substrate such that they are apart from each other; a second step of sequentially forming a light-blocking layer over a support substrate, a resin layer covering the light-blocking layer, and a first coloring layer and a second coloring layer over the resin layer; a third step of bonding the substrate and the support substrate to each other with a liquid crystal layer containing liquid crystal, monomers, and a polymerization initiator positioned therebetween; a fourth step of performing light irradiation from the support substrate side so that the monomers in the liquid crystal layer are polymerized in a region not shielded by the light-blocking layer; and a fifth step of performing separation between the resin layer and each of the support substrate and the light-blocking layer to remove the support substrate and the light-blocking layer.

Abstract: In a light-emitting device where reflective electrodes are regularly arranged, occurrence of interference fringes due to reflection of light reflected by the reflective electrode is inhibited. A surface of the reflective electrode of a light-emitting element is provided with a plurality of depressions. The shapes of the plurality of depressions are different from each other and do not have rotational symmetry. Irregularity of the surface shape of the reflective electrode is increased, which inhibits interference of light reflected by the reflective electrode. To form the plurality of depressions in the surface of the reflective electrode, for example, a surface of an insulating layer that is a base of the reflective electrode is made uneven. Reflecting the surface shape of the insulating layer, the reflective electrode has an uneven surface.
