TECHNICAL FIELD

Embodiments of the present disclosure relate to an array substrate and a display device.

BACKGROUND

In a display panel, for example, in a liquid crystal display panel of an ADS display mode, in order to better avoid the influence of signal lines such as data lines and gate lines on the operation of pixel electrodes, an insulating layer for example is added between the pixel electrodes and the signal lines such as the data lines and the gate lines; the insulating layer is usually required to have a certain thickness for the purpose of reducing the above-mentioned influence, and this increases a thickness of the display panel, and is disadvantageous for thinning the display panel and a display device.
