Thin-film transistor array substrate

Abstract

The invention relates to a thin film transistor array substrate, comprising a substrate, a plurality of scanning lines, a plurality of data lines and a plurality of picture element structures. The scanning lines are composed of first conducting layers; each data line comprises a plurality of first conductors and a plurality of second conductors; wherein, the first conductors and the second conductors are arranged parallel to each other and are mutually connected in series; the second conductors span the scanning lines; the first conductors are positioned between two adjacent scanning lines; the first conductors and the second conductors are respectively composed of first conducting layers and second conducting layers, and the distance between the first conducting layer and the substrate is shorter than the distance between the second conducting layer and the substrate. Each picture element structure comprises a thin film transistor and a picture element electrode; the thin film transistor is electrically connected with the corresponding scanning lines and corresponding second conductors; the picture element electrode is electrically connected with the thin film transistor and at least part of the picture element electrode stretches to the upper part of the adjacent first conductor. The thin film transistor array substrate can maintain the aperture ratio of the display area andeffectively reduce crosstalk.

Description

Thin film transistor array substrate Technical field The present invention relates to a thin film transistor array substrate, and in particular to a thin film transistor array substrate with data lines connected in series with non-coplanar film layers. Background technique In order to meet the requirements of modern products for high speed, high performance, lightness, thinness and shortness, all electronic components are actively developing towards miniaturization. Various portable electronic devices have gradually become mainstream, such as notebooks, cellphones, electronic dictionaries, personal digital assistants (PDAs), webpads and tablet computers ( TabletPC) and so on. For the image display of portable electronic devices, in order to meet the demand for miniaturization of products, flat-panel displays with excellent space utilization efficiency, high image quality, low power consumption, and no radiation have been widely used. Among them, liquid crystal display (LCD) ...
