Abstract: A liquid crystal display apparatus has an improved repair success rate. In the liquid crystal display apparatus, a pixel electrode is electrically connected to a drain electrode of a thin-film transistor. The drain electrode has a substantial correction site which is narrowed in width. An opening is formed in a certain region of said pixel electrode, overlying the substantial correction site of the drain electrode, the opening being in contact with the outer periphery of the pixel electrode.

Abstract: 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.
