Abstract
An active matrix substrate includes a touch electrode disposed in a pixel region, a frame touch electrode disposed in a frame region, and a dummy array segment disposed in the frame region. The frame region includes a first dummy region, provided in a position adjacent to the pixel region, where the frame touch electrode is disposed and a second dummy region provided in a position opposite to the pixel region across the first dummy region. In the second dummy region, the frame touch electrode is not disposed, but the dummy array segment is disposed.
