Active matrix substrate, display panel with touch sensor function, and method of manufacturing active matrix substrate

Abstract

An active matrix substrate is to be mounted on a display panel with a touch sensor function. The active matrix substrate includes a first layer provided with a touch sensor line, a second layer being above the touch sensor line and being provided with a pixel electrode, and a common electrode as a third layer formed between the first layer and the second layer. The common electrode functions as a touch sensor electrode by being connected to the touch sensor line and also functions as a counter electrode of the pixel electrode. The active matrix substrate further includes a first insulating layer formed between the first layer and the third layer, and a second insulating layer formed between the second layer and the third layer. The first insulating layer is formed of an organic resin film.
