Abstract

The invention discloses a detection circuit structure of a liquid crystal display panel and the liquid crystal display panel. The detection circuit structure comprises a first lead wire layer and a second lead wire layer, wherein the first lead wire layer possesses a plurality of signal lead wires; and the second lead wire layer possesses a plurality of test lead wires corresponding to the plurality of signal lead wires. In the plurality of test lead wires, first ends of the at least two test lead wires are connected to the corresponding signal lead wires through a gating unit respectively, and the first ends of the rest test lead wires are connected to the corresponding signal lead wires respectively. Second ends of the test lead wires are connected to a detection terminal used for inputting a test signal. The test lead wire connected to the gating unit transmits the test signal and is started so that the test lead wire and the corresponding signal lead wire are electrically connected. By using a detection circuit structure, a problem that HVA orientation generates an abnormity because of ESD electrostatic discharge is solved, an influence of an array test process on an HVA orientation process is avoided and manufacturing cost is saved.

Description

technical field [0001] The invention belongs to the field of production and manufacture of liquid crystal displays, and in particular relates to a detection circuit structure of a liquid crystal display panel and a liquid crystal display panel with the detection circuit structure.
