PROBLEM TO BE SOLVED: To provide an active matrix substrate, attaining precharge function and inspection function, and to provide a method for inspecting the substrate. SOLUTION: The active matrix substrate comprises a data line drive circuit (101), provided on one end side of a plurality of data lines (35), and an inspection cum precharge circuit (201) provided on the other end side. A releasing or disconnection inspection of the plurality of the data lines is performed (i) by normally operating the data line drive circuit, applying prescribed voltage on a precharge signal line as all of a plurality of precharge switches are turned on and measuring current flowing in a pixel signal line, or (ii) by making the data line drive circuit oparate normally, applying a prescribed voltage on the pixel signal line with all of a plurality of precharge switches, driven simultaneously by a precharge circuit drive signal, turned on, and by measuring the current flowing in the precharge signal line.
