Array substrate, display device and manufacturing method

Abstract

The embodiment of the invention discloses an array substrate, a display device and a manufacturing method, and relates to the field of liquid crystal display. By means of the array substrate, the display device and the manufacturing method, the pixel opening area can be enlarged, and thus the aperture opening ratio of a liquid crystal display is increased. The array substrate comprises a plurality of common electrodes, a plurality of rows of common electrode lines, gate insulation layers and a plurality of columns of data lines. The data lines are arranged between every two columns of sub pixel regions, the common electrodes on the same row are connected through one common electrode line, connection lines parallel to the data lines and connected with the common electrode lines are further arranged between every two columns of sub pixel regions, the connection liens are separated from the data lines through source drain electrode insulating layers, the gate insulation layers and the source drain insulation layers corresponding to the overlapping regions of the connection lines and the common electrode lines are provided with via holes, and the connection lines are connected with the rows of common electrode lines through the via holes.

Description

[0001] This application is a divisional application for a patent application with a filing date of 2012-11-16, an application number of 201210466240.1, and an invention title of "array substrate, display device and manufacturing method". technical field [0002] The invention relates to the field of liquid crystal display, in particular to an array substrate, a display device and a manufacturing method. Background technique [0003] With the continuous development of electronic technology, liquid crystal displays have been widely used in various display fields. A thin film transistor (Thin Film Transistor, TFT) array substrate is an important part of a liquid crystal display. Wherein, the array substrate mainly includes common electrodes, common electrode lines, gate lines, data lines, pixel electrodes and thin film transistors. One common electrode line is used to connect the common electrodes of a row of pixel units. Such as figure 1 As shown, in the prior art, in the p...

AI Technical Summary

Problems solved by technology

[0004] During the research and development process, the inventor found that the existing technology has at least the following problems. Since the via hole needs to occupy a certain area of ​​the pixel electrode and the common electrode, the light in the area of ​​this area cannot pass through the light, which in turn leads to a decrease in the aperture ratio of the pixel unit.
