Abstract

The invention discloses a display substrate, a display panel and a preparation method of the display substrate. The display substrate comprises a base layer, an electrode layer, a first wire, a second wire, a first insulating layer, a connection layer, a frame glue layer and a barrier body; the barrier body is at least arranged in one of a first through hole and a second through hole and used for preventing water vapor in the frame glue layer from entering the first through hole and the second through hole. Through the adoption of the display substrate, the display panel and the preparation method of the display substrate, metal at the through holes can be effectively prevented from being corroded by the water vapor in frame sealing glue.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display substrate, a display panel and a preparation method of the display substrate. Background technique [0002] Liquid crystal display devices have many advantages such as thinness, energy saving, and no radiation. Currently, liquid crystal displays are widely used in electronic equipment such as digital TVs, notebook computers, and mobile phones. Narrow bezel design, array substrate row driving technology and color filter matrix design are currently more common technologies and designs for vertical alignment technology liquid crystal displays. [0003] For this type of design, it is necessary to complete the lines and buses of each row of array substrate gate drive circuits within a certain small frame. The higher the display density, the smaller the height of each row, and the shorter the lateral distance of the array substrate gate drive circuits Generall...
