Abstract

A display panel (200) and a manufacturing method therefor. The display panel (200) comprises: a first substrate (210), a second substrate (220), a GOA circuit, a first metal layer (230), a second metal layer (250), a via hole (260), a first transparent electrode (261) and a second transparent electrode (270), wherein the first substrate (210) is provided with an electrostatic protection circuit (31, 32) connected to the GOA circuit, the first metal layer (230) is arranged on the first substrate (210), the via hole (260) is arranged in the first metal layer (230), the first transparent electrode (261) is arranged in the via hole (260), the second transparent electrode (270) is arranged on the second substrate (220), a first region (271) in the second transparent electrode (270) is removed by etching, and the first region (271) corresponds to the first transparent electrode (261).

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel with electrostatic protection and a manufacturing method thereof. Background technique [0002] GOA technology, namely Gate Driver on Array, is a technology that directly integrates the gate driver circuit on the array substrate to drive multiple scan lines of the display panel, eliminating the need to make a driver chip for an external silicon chip. , and reduce the production process, product cost and area around the panel, which is conducive to the manufacture of display products with narrow borders or no borders, improves the high integration of the display panel, and makes the panel thinner. [0003] The operation of GOA circuits generally requires synchronous signals, clock signals, or low-voltage signals. The signal lines that transmit these signals are distributed on the metal traces around the panel, which increases the risk of electrostatic discharge, a...
