Abstract
The present application provides a liquid crystal display (LCD) panel and an LCD device. In the LCD panel, a first metal layer and a second metal layer are connected to a metal connection layer through a first via hole and a second via hole, respectively. A difference between a depth of the first via hole and a depth of the second via hole is smaller than a sum of thicknesses of a gate insulating layer, an active layer, and the second metal layer. Accordingly, the depth of the first via hole is reduced, a length of the meal connection layer in the first via hole is shortened, and an impedance is lowered.
