A method for manufacturing a display device, which does not easily damage an electrode, is provided. In the first step, a terminal electrode, a wiring, and a functional layer are provided over a first substrate; the terminal electrode, the wiring, and the functional layer are electrically connected to one another; an insulating layer is provided over the terminal electrode; a first layer is provided over the terminal electrode and the insulating layer; an adhesive layer is sandwiched between the first substrate and a second substrate; the second substrate and the adhesive layer include a first opening overlapping with part of the first layer; and the insulating layer includes a second opening inside the first opening in a top view. In the second step, part of the first layer is removed by emitting particles having a high sublimation property to the first layer, so that the terminal electrode is exposed.
