Abstract

The invention discloses an ESD (Electronic Static Discharge) protecting unit, an array base plate, a liquid crystal display panel and a display device and belongs to the technical field of liquid crystal display. The invention aims to solve the problem of poor ESD protecting effect during a preparation process of the array base plate. The ESD protecting unit comprises a thin film transistor, a gate line and a data line, wherein a grid electrode of the thin film transistor is exposed in an area formed by the data line and the gate line; a source electrode of the thin film transistor is connected with the data line; a drain electrode of the thin film transistor is connected with the gate line; or the source electrode of the thin film transistor is connected with the gate line and the drain electrode of the thin film transistor is connected with the data line. The liquid crystal display panel comprises the array base plate containing the ESD protecting unit, wherein the drain electrode of the thin film transistor is connected with a direct current negative voltage source in each ESD protecting unit. The ESD protecting unit provided by the invention is applicable to the display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an ESD protection unit, an array substrate, a liquid crystal panel and a display device. Background technique [0002] At present, the manufacturing process of liquid crystal panels mainly includes three processes: array substrate manufacturing process, liquid crystal cell manufacturing process and module assembly process. Among them, in the array substrate preparation process, due to the need to continuously transfer the glass substrate and prepare thin film transistors on the glass substrate; therefore, the glass substrate will be constantly rubbed and moved during the process of transferring the glass substrate and preparing thin film transistors on the glass substrate , so as to continuously generate static electricity; moreover, since the glass substrate is an insulator, the static electricity generated in the array substrate preparation process is slow to dis...
