Problems solved by technology

Therefore, in order to improve the utilization rate of the substrate and reduce the production cost, in the display motherboard, a zero-cut design is often required between adjacent display panels, that is, the cutting line for cutting the display motherboard is aligned with the edge of the display panel. As a result, in some cases, the test via hole (2D Via) of some display panels will remain on the edge of another display panel adjacent to it
The remaining test vias will be corroded by water vapor and then charged, and the charge will be transferred to the black matrix layer (BM) on the opposite color filter substrate, which will cause the black matrix layer to be charged and cause poor display

Abstract

The invention provides a display panel, a manufacturing method thereof and a mask plate. The display panel comprises an array substrate and a color film substrate, wherein one surface, facing the color film substrate, of the array substrate is provided with a through hole for testing; an isolating layer corresponding to the through hole for testing is arranged on one surface, facing the array substrate, of the color film substrate; and the orthographic projection of the through hole for testing on the color film substrate is located in the isolating layer, and the isolating layer is made of an insulating material.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display panel, a manufacturing method thereof, and a mask plate. Background technique [0002] In the context of increasingly fierce competition in the liquid crystal display industry, effectively reducing costs can significantly improve product competitiveness, and improving the utilization rate of substrates (eg, glass substrates) is one of the effective ways to reduce costs. Therefore, in order to improve the utilization rate of the substrate and reduce the production cost, in the display motherboard, a zero-cut design is often required between adjacent display panels, that is, the cutting line for cutting the display motherboard is aligned with the edge of the display panel, As a result, in some cases, the test via hole (2D Via) of some display panels will remain on the edge of another adjacent display panel. The remaining via holes for testing will be corrod...
