In the method for manufacturing a capacitance sensor according to the present invention, after a protection layer is pattern-formed on the surface of a silicon substrate, a first metal layer is formed on the surface of a silicon substrate so as to be opposed to a protection layer non-formed area on which no protection layer is formed and to expose a part of the protection layer non-formed area. After that, a first insulation layer, a metal sacrificing layer, and a second insulation layer, and a second metal layer are formed on the first metal layer in this order. Then, the metal sacrificing layer is removed by supplying a metal etching solution on the metal sacrificing layer. Further, a part of the silicon substrate is removed by supplying a silicon etching solution to the silicon substrate from the portion, from which the metal sacrificing layer is removed, via the protection layer non-formed area exposed by the removal of the metal sacrificing layer.

The invention discloses a flexible display panel and a display device, relates to the technical field of display, and solves the problems that the display state of a display screen cannot be correspondingly adjusted along with the folding operation of electronic equipment, and waste is caused.
