Abstract: A display panel and a liquid crystal display device are provided. The display panel includes a first substrate and a second substrate, a sealant, a display layer, a circuit layer, and an organic film layer. The organic film layer includes vias and planarization portions arranged adjoining the vias. A first conductive layer includes conductive pads, and each conductive pad covers a signal line in at least one via and the planarization portion adjoining the vias. A second conductive layer is disposed on one side of the second substrate. A conductive ball of the sealant is located on the planarization portions and contact the first conductive layer and the second conductive layer. The signal line is electrically connected to the second conductive layer through the conductive pad and the conductive ball.
