In order to solve the problem, in the curved display, a technology of Data Line BM Less (DBS) over Data lines is increasingly adopted, in which routing lines of Indium Tin Oxide (ITO) are covered over the Data lines, the Data lines are shielded by the ITO routing lines, and an array substrate common voltage is provided to the ITO routing lines, so that when the panel normally operates, the potential of the ITO routing lines is always equal to the array substrate common voltage, and thus liquid crystal molecules corresponding to the positions of the ITO routing lines are kept in a non-deflection state, and a purpose of shielding light is achieved.

Referring to fig. 2, the present invention provides an array substrate, including: the liquid crystal display panel comprises a substrate base plate 1, a first metal layer 2 arranged on the substrate base plate 1, a first insulating layer 3 arranged on the substrate base plate 1 and the first metal layer 2, a second metal layer 4 arranged on the first insulating layer 3, a second insulating layer 5 arranged on the second metal layer 4, and a pixel electrode layer 6 arranged on the second insulating layer 5.
Specifically, the first metal layer 2 includes a plurality of scan lines 21 arranged in parallel at intervals and a common electrode line 22 spaced from the scan lines 21, and the second metal layer 4 includes: a plurality of data lines 41 arranged in parallel at intervals, the plurality of scan lines 21 and the plurality of data lines 41 cross each other to define a plurality of pixel units 7 arranged in an array, the pixel electrode layer 6 includes: a plurality of pixel electrodes 61 respectively corresponding to the plurality of pixel units 7 and a plurality of light-shielding electrodes 62 respectively corresponding to the plurality of data lines 41 and shielding the data lines 41; each of the light-shielding electrodes 62 is insulated and spaced from the first metal layer 2, the second metal layer 4, and the pixel electrode 61.
Specifically, the substrate 1 is a transparent substrate, preferably a glass substrate, and the material of the first insulating layer 3 and the second insulating layer 5 is one or a combination of silicon oxide (SiOx) and silicon nitride (SiNx). The material of the first metal layer 2 and the second metal layer 4 is one or a combination of molybdenum, aluminum, titanium and the like. Preferably, the material of the pixel electrode layer 6 is ITO.
Specifically, as shown in fig. 2, 4 and 5, the substrate base board 1 is further provided with a plurality of driving TFTs T10 arranged in an array, and each driving TFT T10 includes: the gate electrode 23 is located on the first metal layer 2, the active layer 31 is located on the first insulating layer 3 above the corresponding gate electrode 23, and the source electrode 42 and the drain electrode 43 are located on the second metal layer 4 and contact both ends of the active layer 31.
Specifically, the driving TFT T10 may be a thin film transistor of various types such as an oxide semiconductor thin film transistor or a low temperature polysilicon thin film transistor.
Specifically, as shown in fig. 2 and 5, each driving TFT T10 corresponds to one pixel unit 7, the gate of each row driving TFT T10 corresponds to one scanning line 21, the source 42 of each column driving TFT T10 corresponds to one data line 41, and the drain of each driving TFT T10 corresponds to the pixel electrode 61 of the corresponding pixel unit 7.
