摘要:
Disclosed herein is a method for detecting a defect of an active matrix liquid crystal panel, the method including a step of inputting a data signal for displaying an image having a luminance level lower than a maximum luminance level to a first signal line while inputting a data signal for displaying a black image to a second signal line and a third signal line, the second signal line and the third signal line adjoining the first signal line, thereby causing pixels corresponding to the first signal line to display a single color. According to the method of the present invention, any defective pixel is displayed darker than normal, owing to a decrease in the transmittance, so that point defects such as S-D leak defects can be easily detected.

Common lines are formed in parallel with gate lines. A line which joins those parallel lines is provided in parallel with source lines on the substrate edge part on the gate line terminals side. Another line which joins the same parallel lines is provided in parallel with source lines on the substrate edge part on the opposite side of the gate line terminals. These two terminals are supplied with a signal which is identical with the common signal being applied to an opposing electrode. Depressed portions are provided for each pixel electrode at positions where the source line and common line intersect with each other or in the vicinity of the source line on both sides thereof.

In the case where a possible defect of a liquid crystal panel is detected, after the liquid crystal panel is put into an oven with the liquid crystal panel being energized, a second inspecting pulse, which has a larger potential difference than a potential difference of a first inspecting pulse applied to a second signal line on an active matrix substrate, is applied to a second signal line. In the above method, since an insulating layer, which is on the verge of breakage, between a source line and the second signal line can be broken, a possible defect of the liquid crystal panel can be detected as a cross bright line by inspection for turning-on in the panel inspecting step. For this reason, in this method, accuracy of detecting a possible defect can be improved, and the number of S-G leaks in the market is decreased greatly, thereby improving display quality of the liquid crystal panel.
