Abstract

The invention discloses a liquid crystal display panel and a testing method thereof. The liquid crystal display panel comprises the components of a substrate; and a plurality of sets of testing units which are formed on the substrate. Each set of testing units in the plurality of sets of detecting units comprise a plurality of signal wires which extend in a first direction and are arranged in a second direction; and a plurality of short-circuit rods, wherein each short-circuit rod is connected with the first end of one signal wire, and furthermore the short-circuit rods are arranged in the first direction in a stepped manner, wherein the plurality of short-circuit rods which are connected with corresponding signal wires in each testing unit are arranged in a line in the second direction, thereby forming a short-circuit rod set. Therefore the liquid crystal display panel and the testing method thereof have advantages of eliminating a process of cutting the signal wires in a liquid crystal display panel testing process, realizing convenient operation and effectively improving utilization rate of the liquid crystal display panel.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display devices, and more particularly, to a liquid crystal display panel and a detection method thereof.
