Problems solved by technology

The inventors have found that using the above method to eliminate crosstalk requires an additional patterning process to form a pattern including the common electrode 11' between the pixel electrode 16' and the data line 14', so the number of masks used and the number of processes need to be increased , resulting in an increase in the production cost of the display panel

Embodiment 1

[0065] The embodiment of the present invention provides a display panel, which can reduce the manufacturing cost of the display panel on the premise of eliminating the crosstalk phenomenon. The display panel provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] The display panel includes an array substrate, such as figure 2 , image 3 with Figure 4 As shown, the array substrate includes a plurality of film layers sequentially formed on the first base substrate 10, wherein the data line 131 and the drain electrode 132 are located in the same film layer, and the gate line 151, the gate electrode 152 and the first common electrode 153 are located in the same film layer. In the same film layer, the film layer where the gate line 151, the gate electrode 152 and the first common electrode 153 are located is located between the film layer where the data line 131 and the drain electrode 132 are located...

Embodiment 2

[0086] In order to prepare a display panel with the above structure, an embodiment of the present invention also provides a method for manufacturing a display panel, such as Figure 7 As shown, the manufacturing method of the display panel includes the following steps:

[0087] Step S701, forming a first metal layer on the substrate, and forming a pattern including a data line and a drain electrode through a patterning process.

[0088] First, the first metal layer is formed on the substrate by sputtering or thermal evaporation. Generally, the first metal layer is deposited by using metals such as Cr, W, Ti, Ta, Mo, Al, Cu, and their alloys. The thickness of a metal layer is

[0089] Then, coat photoresist on the first metal layer, use a mask with patterns including data lines 131 and drain electrodes 132 to cover the first metal layer coated with photoresist, and go through exposure, development, etching, etc. After the step, a pattern including the data line 131 and the drain ele...

Abstract

An embodiment of the invention discloses a display panel, a production method thereof and a display device, and relates to the technical field of display. Production cost of the display panel can be reduced on the premise of crosstalk elimination. The display panel comprises an array substrate. The array substrate comprises a plurality of film layers sequentially formed on a first substrate. A data line and a drain electrode are positioned on the same film layer. A grid line, a grid electrode and a first common electrode are positioned on the same film layer. The film layer where the grid line, the grid electrode and the first common electrode are positioned is positioned between the film layer where the data line and the drain electrode are positioned and the film layer where a pixel electrode is positioned.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] The display panel in the liquid crystal display is used to display pictures, and the display panel mainly includes an array substrate and a color film substrate. Among them, the array substrate is composed of a base substrate and a plurality of film layers formed on the base substrate. [0003] figure 1 It is a cross-sectional view of the data line portion on the array substrate. A common electrode 11', a gate insulating layer 12', an active layer 13', a data line 14', and a passivation layer 15' are sequentially formed on the base substrate 10' 和Pixel electrode 16'. Wherein, the common electrode 11' is located on the same film layer as the gate line and the gate on the array substrate, that is, the common electrode 11', the gate line and the gate are simultaneously formed on t...
