Touch panel and method for manufacturing touch panel

Abstract

A touch panel capable of performing display and sensing along a curved surface or a touch panel that maintains high detection sensitivity even when it is curved along a curved surface is provided. A flexible display panel is placed along a curved portion included in a surface of a support. A first film layer is attached along a surface of the display panel by a bonding layer. Second to n-th film layers (n is an integer of 2 or more) are sequentially attached along a surface of the first film layer by bonding layers. A flexible touch sensor is attached along a surface of the n-th film layer by a bonding layer.
