Abstract: A liquid crystal panel includes an active matrix substrate including a gate driver circuit, a demultiplexer circuit, and a gate switch circuit. The active matrix substrate includes a non-display region and a testing terminal region located outside the non-display region, has first and second in-panel testing terminals in the non-display region, and has first and second out-panel testing terminals in the testing terminal region. The second out-panel testing terminal is connected to the gate driver circuit. The first out-panel testing terminal is connected to the demultiplexer circuit. The second in-panel testing terminal is connected to the gate switch circuit. The first in-panel testing terminal is connected to the demultiplexer circuit.

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.
