The invention discloses a method for preparing an array substrate, an array substrate and a display device. The method includes: setting a plurality of thin film transistors arranged in an array on a substrate; depositing a first transparent electrode layer on the substrate, and performing a first patterning process on the first transparent electrode layer, so as to form a plurality The first electrode connected to the drain of the thin film transistor, and the connection electrode connected to the adjacent first electrodes; a functional structure is provided on the side of the first transparent electrode layer away from the substrate; and the connection The electrodes are subjected to a second patterning process, and the connection electrodes are disconnected to form protruding connection parts at the edges of the first electrodes. Therefore, various defects caused by electrostatic breakdown during the preparation process of the array substrate can be eliminated by using a simple preparation process.
Description
technical field [0001] The present invention relates to the field of liquid crystal display, in particular, to a method for preparing an array substrate, an array substrate, and a display device. Background technique [0002] Liquid crystal display has the advantages of thin body, low power consumption, low radiation and soft picture, and has been developed rapidly in recent years. The main structure of the liquid crystal display is a display panel, and the display panel includes a backlight module, an array substrate and a color filter substrate arranged in opposite boxes, and liquid crystal molecules encapsulated between them. The array substrate is provided with gate lines, signal lines, and thin film transistors. The gate lines and signal lines are used to define a plurality of pixel areas, each pixel area includes a pixel electrode, and the thin film transistor is used as a switching device to control the pixel electrode. and the common electrode form an electric field...
