Abstract
The present disclosure provide a liquid crystal display panel, a manufacturing method thereof, and a liquid crystal display device. In the liquid crystal display panel, a projection of the pull-down signal line on the substrate is spaced apart from a projection of any wiring in the gate layer on the substrate, so that no other metal is placed under the pull-down signal line, and the thickness of the photoresist on the pull-down signal line can be increased accordingly, thus the width of the pull-down signal line can be increased, and disconnection and failure of the pull-down signal line can be avoided.
