    摘要: This invention provides an inspecting method, an inspecting apparatus, and a defect correcting method, for an active matrix substrate including: a gate bus line; a source bus line; a pixel electrode; a switching element for driving the pixel electrode; and a pair of electrodes constituting an auxiliary capacitance. The inspecting method includes: a step of disposing a counter substrate having a face on which a counter electrode is formed so that the face faces the active matrix substrate with a liquid crystal layer interposed therebetween, and connecting signal supplying terminals to gate bus lines and source bus lines and the counter electrode; and a detection step of detecting a defect on the active matrix substrate by performing at least one of a first signal generating step, a second signal generating step, and a third signal generating step. The first, second, and third signal generating steps all include alternately applying an ON signal for turning on the switching element and an OFF signal for turning off the switching element to the gate bus line. The first signal generating step includes applying a first detecting signal having a voltage which changes before the ON signal is applied to the source bus line. The second signal generating step includes applying a second detecting signal having a voltage which changes before and after the ON signal is applied. The third signal generating step includes applying a third detecting signal having a voltage which changes after the ON signal is applied.

    摘要: An active matrix board comprises pixel electrodes (9) that are disposed in a matrix fashion on an insulating substrate (1), scan lines (23) which are disposed in a parallel manner between the individual pixel electrodes (9), addition capacity lines (31), and signal lines (11) which intersect the scan lines (23) and the addition capacity lines (31). Each scan line (23) comprises a lower scan line (2) which is discontinuously disposed and an anodizable upper scan line (3) that covers the lower scan line (2) and is continuously disposed. Similarly, each addition capacity line (31) comprises a lower line (29) which is discontinuously disposed and an anodizable upper line (30) that covers the lower line (29) and is continuously disposed. Should a segment of a lower line (2, 29) be eroded during etching, the discontinuous disposition of other segments of the lower line (2, 29) precludes the other segments from being subject to erosion.
