Description

一种液晶显示面板 技术领域
本发明涉及显示器技术领域，特别是涉及一种液晶显示面板。
 背景技术
在TFT-LCD（薄膜晶体管液晶显示器）面板制作过程中，玻璃基板在移动和搬运过程中，容易与机台或者空气摩擦产生静电。当静电在玻璃上积累到一定程度，就会产生很大的电位差，积累的电荷具有足够的能量离开原来的位置而与极性相反的电荷中和，由于电荷移动在很短的时间内完成，移动过程中产生了很大的电流，导致电荷放电，且由于放电过程具有破坏性且发生的位置难以预测。如果发生在金属线交叠的地方，很容易静电击穿金属线使其短路，导致功能异常，增大生产成本。
因此，有必要提供一种液晶显示面板，以解决现有技术所存在的问题。
