The invention discloses an array substrate, a liquid crystal display panel and a display device. The array substrate comprises a signal line, a wiring terminal gasket corresponding to the signal line and a peripheral routing line connected with the signal and the corresponding wiring terminal gasket. In the array substrate, since the peripheral routing line is composed of multiple leads which are arranged in different layers and in series connection, compared with an existing integral peripheral routing line, the peripheral routing line has the advantage that even if the wiring terminal gasket exposed to the air is corroded as moisture and oxygen in air are in contact, corrosion cannot extend inwardly to the signal line along the peripheral routing line so as to avoid the problem of abnormal display caused by the fact that the signal line is corroded. Besides, the peripheral routing line is arranged to be composed of the multiple leads arranged in different layers, compared with the integral peripheral routing line in the prior art, the peripheral routing line has the advantage that accumulation of static electricity on the peripheral routing line can be reduced since each lead is small in area.
