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： A liquid crystal display device incorporating an active matrix substrate having an inter-layer insulating film between a pixel electrode and gate and source signal lines. In this liquid crystal display device, the source signal line has a double-layer structure of an upper-layer line and a lower-layer line, but the upper-layer line is eliminated at the intersection of the gate signal line and the source signal line. This structure prevents a decrease in the thickness of the inter-layer insulating layer on the intersection of the gate signal line and the source signal line.

摘要： An object of the present invention is to attain proper display free from improper display conditions, such as crosstalk, improper contrast and uneven display. Another object is to obtain a high aperture ratio by reducing a margin for bonding. Light shielding films are used to cover the overlap portion of the source electrode and the semiconductor layer and the overlap portion of the drain electrode and the semiconductor layer of a bottom gate type TFT device, such as a staggered type. This structure can suppress off-current due to light leakage, and can prevent deterioration of display quality.
