A display panel including first to third conductive films is provided, which includes: a first signal line including a first portion that includes the first conductive film, an intermediate portion that includes at least two of the first to the third conductive films (“intermediate portion films”), and a contact portion that contacts an output terminal of a driving circuit and includes the intermediate portion films except for at least one of the intermediate portion films; a second signal line intersecting the first signal line and including the second conductive film; a switching element connected to the first and the second signal lines; and a pixel electrode connected to the switching element and including the third conductive film.
