The invention discloses an LCD (
liquid crystal display) panel and a manufacturing method thereof. The LCD panel comprises a first border scanning line, a first
dielectric layer and a second border scanning line, wherein the first border scanning line is manufactured in a border area, the first border scanning line
and gate lines are formed in a same photoetching step, and the first border scanning line is connected with part of thin-film transistors by a corresponding grid line; the first
dielectric layer covers the first border scanning line; the second border scanning line is arranged on the surface of the first
dielectric layer, and connected with the gate electrodes of remaining thin-film transistors by remaining gate lines; and the first border scanning line and the second border scanning line are made of a same
metal material. In the invention, the widths and thicknesses of the two
layers of scanning lines can be designed to be same, and because the developing and photoetching conditions are same, the widths of the two
layers of scanning lines subjected to photoetching are more consistent, so that the resistances of the two
layers of scanning lines are closer, thereby avoiding the occurrence of a situation that horizontal stripes are displayed non-uniformly; and under the premise of narrowing a border of the LCD panel, the display effect of the LCD panel is improved.
