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.

Abstract: A liquid crystal display panel and a manufacturing method thereof, and a frameless liquid crystal display device are provided. The liquid crystal display panel includes an array substrate, a counter substrate, and a liquid crystal layer. The array substrate includes a first region and a second region. The counter substrate includes a third region and a fourth region. A black matrix covers one side of the fourth region, and a metal light-shielding portion is disposed on one side of the array substrate facing toward the counter substrate. The metal light-shielding portion covers the second region and a part of the first region adjacent to the second region, and a side-edge of the metal light-shielding portion near the first region is located below the black matrix. Through adding the metal light-shielding portion, light leakage occurring on edges of a frameless liquid crystal display device is solved, and display quality is improved.
