Abstract

The invention provides a making method for a thin film transistor array substrate. The making method includes the steps that a thin film transistor array, an array-substrate row driving circuit and an array test circuit are respectively made on a base substrate; the array test circuit is respectively connected with the thin film transistor array and the array-substrate row driving circuit, and the thin film transistor array and the array-substrate row driving circuit are tested through the array test circuit; after testing is completed, the array test circuit and the substrate area of the array test circuit are cut off. In the making method, before the thin film transistor array substrate is formed through cutting, the prepared thin film transistor array and the array-substrate row driving circuit are tested, and resource wasting caused when a liquid crystal display is made of a poor thin film transistor array substrate is effectively avoided; meanwhile, after the thin film transistor array substrate is tested, the array test circuit is cut off, and therefore a frame of a liquid crystal display can be narrower.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a thin film transistor array substrate. Background technique [0002] A thin film transistor liquid crystal display (TFT-LCD) mainly includes a thin film transistor array substrate, a color filter array substrate and a liquid crystal placed between them, wherein the thin film transistor array substrate includes a thin film transistor array and a row driving circuit of the array substrate. At present, when making a thin-film transistor array substrate, an array test circuit will be fabricated on the substrate at the same time, and the thin-film transistor array substrate and the array test circuit will be cut and boxed together to form a liquid crystal display. The array test circuit is used to test the thin-film transistor array. The substrate is tested, and if the TFT array substrate is found to be abnormal, the manufactured liquid cryst...
