COMPOSITE STRUCTURE AND TOUCH DEVICE

摘要

A composite structure and a touch device are provided. The composite structure includes a substrate and a transparent conductive pattern layer. The substrate has a central area and a peripheral area. The transparent conductive pattern layer is disposed on the substrate and has a plurality of recess-portions. The recess-portions are disposed on a side surface of the transparent conductive pattern layer away from the substrate and at least located in the peripheral area. A depth of each of the recess portions is smaller than or equal to a thickness of the transparent conductive pattern layer. A width of each of the recess portions is between 100μm and 1000μm, and the recess portions are arranged in a ring-shape or arranged in an array.
