Patent ID: 11899296

Abstract:
A semiconductor device including a large display portion with improved portability is provided. The display device includes a first display panel, a second display panel, and an adhesive layer. The area of the second display panel is larger than the area of the first display panel. The first display panel includes a first substrate, a second substrate, and a reflective liquid crystal element and a first transistor each positioned between the first substrate and the second substrate. The second display panel includes a first resin layer having flexibility, a second resin layer having flexibility, and a light-emitting element and a second transistor each positioned between the first resin layer and the second resin layer. The liquid crystal element has a function of reflecting light toward the second substrate side. The light-emitting element has a function of emitting light toward the second resin layer side. The first substrate and part of the second resin layer are bonded to each other with the adhesive layer.
