Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, relates to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] In recent years, the rapid development of information and communication technology has increased the demand for various types of display devices. Currently common display devices include: a cathode ray tube display, a liquid crystal display (Liquid Crystal Display, LCD), a plasma display, an electroluminescent display, and a vacuum fluorescent display. Among them, LCD has gradually become the mainstream of display device development due to its high-definition, true-color video display, thin and light appearance, low power consumption, and no radiation. [0003] An LCD generally includes a liquid crystal display panel for displaying pictures and a circuit part for supplying signals to the liquid crystal display panel. The liquid crystal display...
