TOUCH SENSOR AND TOUCH PANEL

摘要

A thin touch panel is provided. A touch panel with a simple structure is provided. The number of components of a touch panel is reduced. Each of a pair of wirings of a touch sensor is positioned closer to a substrate supporting light-emitting elements than a common electrode is, and includes a portion positioned between two adjacent pixel electrodes in a plan view. Furthermore, an island-like structure body with an inverse tapered shape is provided over each of the pair of wirings. A conductive layer in an electrically floating state is provided over the structure body. Each conductive layer has a portion overlapping with one of the pair of wirings. Moreover, the conductive layer and the common electrode are formed using the same conductive film.
