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.
