Disclosed are an array substrate and a preparation method therefor, and a display panel. The array substrate is provided with a functional layer (115) between an active layer (114) and a gate insulation layer (116), such that when the active layer (114) is being etched, the active layer (114) is protected to prevent damage to the active layer (114). In addition, the functional layer (115) enables a source-drain layer (119) to be in conduction with the active layer (114), such that a transistor in the array substrate works normally, thereby solving the technical problem of existing display panels having a thin film transistor with reduced performance due to damage to the active layer (114) during the preparation process. L'invention concerne un substrat de réseau et son procédé de préparation, et un panneau d'affichage. Le substrat de réseau est pourvu d'une couche fonctionnelle (115) entre une couche active (114) et une couche d'isolation de grille (116), de sorte que, lorsque la couche active (114) est gravé
