The purpose of the invention is to manufacture the device having a resin substrate without using expensive machine like laser apparatus and so forth, and to raise a yield rate of the material. The structure is as follows.A device having a resin substrate:in which the resin substrate has a surface, on which a functional layer is formed, and a back surface, which is rear side from the surface,the back surface has a peripheral area and an inner area, which is located inner side than the peripheral area in a plan view,the peripheral area has a rough surface whose surface roughness is larger compared with a surface roughness of the inner area. |
