Abstract
A method for manufacturing an active matrix substrate including a thin film transistor for each pixel, and a first electrode and a first wiring line for touchscreen panel function includes: forming a transparent electrically conductive film on an interlayer insulating layer and within a first contact hole; forming, on a portion of the transparent electrically conductive film, an upper wiring portion to become an upper layer of the first wiring line; patterning the transparent electrically conductive film to make a pixel electrode and form a lower wiring portion to become a lower layer of the first wiring line; forming a dielectric layer covering the pixel electrode and the first wiring line and having a second contact hole through which a portion of the first wiring line is exposed; and forming a common electrode which is electrically connected to the first wiring line within the second contact hole.
