Problems solved by technology

Existing methods for improving the aperture ratio of TFT display devices are mainly realized by reducing the width of the black matrix, but using this method to increase the aperture ratio of TFT display devices is very limited, and, because the width of the black matrix is ​​reduced, This method is easy to cause the TFT substrate and the CF substrate to shift during the assembly process and cause light leakage.

Abstract

The present invention provides a liquid crystal display and an array substrate thereof. The array substrate includes a plurality of data lines arranged along a first direction and a plurality of gate lines arranged along a second direction, and the data lines are arranged to cross the gate lines. And define a plurality of pixel regions arranged in an array, the array substrate also includes a thin film transistor, a pixel electrode and a first transparent electrode, the thin film transistor and the pixel electrode are located in the pixel region, and the first transparent electrode is located along the first transparent electrode. arranged in one direction, the first transparent electrode is located between any two adjacent pixel electrodes in the first direction. In the liquid crystal display proposed by the present invention, by adding the first transparent electrode, the display area of ​​the liquid crystal display can be extended to the partial area where the first transparent electrode is located, which increases the display area of ​​the liquid crystal display compared with the prior art, thereby improving the performance of the liquid crystal display. Opening rate.

Description

technical field [0001] The invention relates to the technical field of preparation technology of liquid crystal displays, in particular to a liquid crystal display and an array substrate thereof. Background technique [0002] The aperture ratio of a TFT display device is an important indicator that determines the quality of a TFT display device. A high aperture ratio can save power consumption of the display device and prolong the service life of the display. Such as figure 1 As shown, the black matrix in the TFT display device is mainly to shield the signal lines and thin film transistors in the TFT display device, wherein the display area of ​​the TFT display device is mainly the area where the pixel electrodes are located. Existing methods for improving the aperture ratio of TFT display devices are mainly realized by reducing the width of the black matrix, but using this method to increase the aperture ratio of TFT display devices is very limited, and, due to reducing th...
