Abstract

An array substrate and a display device are disclosed. The array substrate includes a base substrate, a transmitting touch electrode pattern and a receiving touch electrode pattern; the transmitting touch electrode pattern is formed on a first face of the base substrate, the receiving touch electrode pattern is formed on a second face of the base substrate, and the first face and the second face are opposite to each other. With the array substrate, shadows of the transmitting touch electrode pattern and the receiving touch electrode pattern can be eliminated or alleviated, and the transmitting touch electrode pattern and the receiving touch electrode pattern can be avoided from being scratched.

Claims

1. An array substrate, comprising:

a base substrate, and

a transmitting touch electrode pattern and a receiving touch electrode pattern;

wherein the transmitting touch electrode pattern is formed on a first face of the base substrate, the receiving touch electrode pattern is formed on a second face of the base substrate, and the first face and the second face are opposite to each other.

2. The array substrate claimed as claim 1, further comprising a display driving signal line,

wherein the transmitting touch electrode pattern or the receiving touch electrode pattern is located on the same face as the display driving signal line of the array substrate, and is formed below the display driving signal line.

3. The array substrate claimed as claim 1, wherein wirings of the transmitting touch electrode pattern and wirings of the receiving touch electrode pattern are perpendicular to each other.

4. The array substrate claimed as claim 2, wherein wirings of the transmitting touch electrode pattern and wirings of the receiving touch electrode pattern are perpendicular to each other.

5. A display device, comprising the array substrate claimed as claim I.

6. The display device claimed as claim 5, wherein the display device is a liquid crystal display device.

7. The display device claimed as claim 6, further comprising a polarizer, wherein the array substrate includes a display driving signal line, and the polarizer is attached to a face that is opposite to the display driving signal line of the array substrate.
