Abstract

The present application relates to an array substrate. In the fan-out region of the array substrate, first metal lines, second metal lines and common electrode lines insulated from each other are sequentially stacked. On any cross-section of the extension path of the first metal lines , the first metal line includes a first end point and a second end point in the first direction, the second metal line does not exceed the first end point in the first direction, and the common electrode line is The first direction does not exceed the second endpoint. The second metal line and the common electrode line form a cross-stacked structure in the first direction, which can avoid the conduction of the two in the case of poor cutting, and ensure that the array substrate will not be short-circuited. The present application also relates to a liquid crystal display and an electronic device equipped with the above-mentioned array substrate.

Description

technical field [0001] The present application relates to the field of liquid crystal panels, in particular to an array substrate with double-layer metal wiring in a fan-out region, a liquid crystal display equipped with the array substrate, and an electronic device equipped with the liquid crystal display. Background technique [0002] In the current environment where the liquid crystal display industry generally pursues narrow bezels and large screen-to-body ratios, the array substrate, an important part of liquid crystal displays, has become the main object of research. The array substrate is provided with a fan-out area at the frame, and the timing controller transmits the scanning signal and the data signal to each pixel through the wiring in the fan-out area, so as to realize the display function of the liquid crystal display. [0003] In order to reduce the size of the fan-out area, some array substrates use double-layer metal wires to reduce the total area of ​​the w...
