Abstract: A display device with high visibility regardless of the ambient brightness is manufactured at low cost. A method for manufacturing a display device that includes a first display element, a second display element, and an insulating layer is provided.The first display element includes a first pixel electrode that reflects visible light, a liquid crystal layer, and a first common electrode that transmits visible light. The second display element includes a second pixel electrode that transmits visible light, a light-emitting layer, and a second common electrode that reflects visible light. The first common electrode is formed over a first substrate. A separation layer that reflects visible light is formed over a formation substrate, the insulating layer is formed over the separation layer, and the second display element is formed over the insulating layer. The formation substrate and a second substrate are bonded to each other with an adhesive. Then, the formation substrate and the separation layer are separated from each other. The exposed separation layer is processed into the first pixel electrode. The liquid crystal layer is positioned between the first common electrode and the first pixel electrode and the first substrate and the second substrate are bonded to each other with an adhesive to form the first display element.

Abstract: A highly reliable light-emitting device is provided. A light-emitting device with high resistance to repeated bending is provided. A light-emitting device in which cracks are less likely to occur even in a high-temperature and high-humidity environment is provided. The light-emitting device includes a light-emitting element between a pair of insulating layers. The pair of insulating layers is sandwiched between a pair of bonding layers. The pair of bonding layers is sandwiched between a pair of flexible substrates. At least one of the insulating layers has compressive stress. At least one of the bonding layers has a glass transition temperature higher than or equal to 60° C. At least one of the substrates has a coefficient of linear expansion less than or equal to 60 ppm/K.
