Title
(EN) Display panel
(ZH) 显示面板
Abstract
(EN) The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a plurality of parallel scanning lines, a plurality of parallel data lines, a common electrode and a plurality of connecting lines, wherein the scanning lines are perpendicular to the data lines in different planes, and a circle of second metal layer is further arranged in the non-display regionon the same layer as the data lines; the plurality of connecting lines are arranged in parallel to the data lines; and each scanning line is provided with a plurality of protruding structures at intervals in the first direction. The display panel has the beneficial effects that the connecting lines and the scanning lines are perpendicularly arranged, so that the connecting lines and the scanninglines are prevented from being arranged in parallel, and the situation that etching liquid is left in the display panel and the display quality of the display panel is affected due to the fact that closed spaces are formed at positions where the connecting lines are close to the scanning lines is avoided; besides, the plurality of protruding structures are arranged on the scanning lines at intervals in the first direction, the first protruding structures face the positive direction of the second direction, and the second protruding structures face the negative direction of the second direction, so that the possibility that etching liquid remains in the display panel is further reduced, and the production yield of the display panel is improved.
(ZH) 一种显示面板及其制作方法,显示面板包括:多条相互平行的扫描线、多条相互平行的数据线、公共电极以及多条连接线;扫描线与数据线异面垂直,与数据线同层的非显示区内还设置有一圈第二金属层;多条连接线均平行于数据线进行设置;扫描线沿第一方向间隔设置有多个凸起结构;有益效果为:将连接线与扫描线垂直设置,避免连接线与扫描线平行设置,连接线与扫描线相近的位置形成密闭空间,导致蚀刻液残留在显示面板内,影响显示面板的显示质量;此外,在扫描线沿第一方向上间隔设置有多个凸起结构,第一凸起结构朝向第二方向的正方向,第二凸起结构朝向第二方向的负方向,进一步减小了蚀刻液残留在显示面板内的可能,提高了显示面板的生产良率。
