The invention discloses an integrated piece, a manufacturing method of the integrated piece and a method for manufacturing a touch screen by the adoption of the integrated piece. The integrated piece is composed of a polaroid, optical cement and release films arranged at the outer side of the polaroid and the outer side of the optical cement, wherein the polaroid and the optical cement are attached to each other. When the touch screen is manufactured by the adoption of the integrated piece, the release film which is arranged in the integrated piece and located on one side, away from the optical cement, of the polaroid is peeled off and then pasted to the light emitting side of a liquid crystal display panel, then the release film on the other side is peeled off, a touch panel is pasted to the optical cement of the integrated piece, and then manufacturing of the touch screen is finished. Compared with the mode that the pasting technology is conducted three times in the prior art, manufacturing of the touch screen can be finished by conducting the pasting technology only twice. On one hand, the number of devices used for implementing the pasting technology can be decreased, and on the other hand, the productivity can be improved. Meanwhile, only the two films are peeled off in the pasting process, so that resource waste is reduced. Furthermore, the integrated piece can be detected independently before being pasted to the liquid crystal display panel, and the product yield is improved conveniently.
