THIN-FILM TRANSISTOR ARRAY SUBSTRATE AND MANUFACTURING METHOD THEREOF

摘要

The present invention discloses a thin-film transistor array substrate and a manufacturing method thereof. The thin-film transistor array substrate has scanning lines and data lines. The scanning lines are formed by a first metallic layer. The data lines are formed by a second metallic layer. Each of the first and the second metallic layers has a multilayer structure. The multilayer structure includes a primary electrically conductive layer and at least one blocking layer. The primary electrically conductive layer has a restraining metallic layer mounted inside and having a melting point higher than the melting point of the primary electrically conductive layer.
