Problems solved by technology

[0004] In the prior art, the design of increasing the line width of the jumper on the mask plate is adopted, but this method will increase the coupling capacitance between the data line and the common electrode line or between the data line and the scanning line, for example figure 2 As shown, the data line 4 formed at the bridge is wider than the data line 4 at other positions, which increases the coupling capacitance between the data line 4 and the common electrode line 3, and still has adverse effects

Embodiment 1

[0073] Such as image 3 As shown, the array substrate according to one embodiment of the present invention includes:

[0074] base1;

[0075] Gate lines 5, common electrode lines 3 and data lines 4 arranged on the substrate;

[0076] The first spacer layer 10 disposed in the first overlapping area of ​​the common electrode line 3 and the data line 4 and located between the common electrode line 3 and the data line 4, the first spacer layer 10 extends at least in the width direction of the data line 4 One side is extended to a preset length;

[0077] and / or

[0078] The second spacer layer 20 arranged in the second overlapping area of ​​the gate line 5 and the data line 4, and between the gate line and the data line 4, the second spacer layer 20 in the second overlapping area is in the width direction of the data line 4 The top extends to at least one side for a preset length.

[0079] The first spacer layer 10 can increase the distance between the common electrode line ...

Embodiment 2

[0091] Such as Figure 7 As shown, preferably, according to yet another embodiment of the present invention, the array substrate further includes:

[0092] a gate 2 disposed on the substrate 1,

[0093] The second spacer layer 20 is also arranged in the third overlapping area between the gate 2 and the data line 4, and is located between the gate 2 and the data line 4,

[0094] The second spacer layer 20 in the third overlapping region extends to at least one side in the width direction of the data line 4 by a predetermined length.

[0095] Compare Figure 7 and image 3 It can be seen that there is an overlapping area between the gate 2 and the data line 4 in the second embodiment, which is intuitively expressed as Figure 7 The gate 2 in the ratio image 3 The gate 2 is large, not only located under the active layer 6, but also located under the data line 4, the specific cross-sectional view is as follows Figure 9 shown.

[0096] Since multiple pixel areas in the arr...

Abstract

The invention relates to an array baseplate, a manufacturing method thereof and a display device. The array baseplate comprises grid lines, common electrode lines, data lines, a first spacing layer and / or a second spacing layer, the grid lines, the common electrode lines and the data lines are arranged on a substrate, the first spacing layer is arranged in an overlapped area of the common electrode lines and the data lines and positioned between the common electrode lines and the data lines and extends to at least one side by preset length in the width direction of the data lines, and the second spacing layer is arranged in an overlapped area of the grid lines and the data lines and positioned between the grid lines and the data lines and extends to at least one side by preset length in the width direction of the data lines. By arranging the first spacing layer and / or the second spacing layer, when a data line metal layer is exposed, width difference of the data lines caused by difference in light reflectivity of common electrode layer metal and / or grid line layer metal and data line layer metal is reduced, so that width uniformity of the data lines is improved, risk of breaking of the data lines is lowered, and product yield is increased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate, a display device and a manufacturing method of the array substrate. Background technique [0002] TFT (Thin Film Field Effect Transistor) driven display devices are currently the mainstream technology in the display field. A thin film field effect transistor display usually includes a color filter substrate and a TFT array substrate. The TFT array substrate includes a plurality of pixel units, and each pixel unit corresponds to a TFT. When a certain voltage is applied to the gate of the TFT, when the gate voltage reaches the threshold voltage, the channel is turned on (that is, the active layer is turned on), thereby turning on the source and drain, and the signal in the data line is transmitted to the TFT through the source. The drain, and further controls the pixel electrode electrically connected to the drain. The voltage difference between the ...
