The invention discloses an array substrate and a display device. Since the orthographic projections of the first grid and the second grid on the base substrate overlap, and both the first grid and the second grid are located on the first active layer between the second active layer and the second active layer, so that the orthographic projections of the first transistor and the second transistor on the substrate overlap, rather than the orthogonal projections of the two transistors on the substrate as in the prior art. In this way, the utilization rate of space can be improved, which is conducive to improving the display resolution and realizing the design of high screen-to-body ratio and narrow border, thereby improving the display effect. Moreover, through the above arrangement, a shielding effect is generated between the first gate and the second gate, that is, the first gate can shield the signal on the second gate from interfering with the first active layer, and the second gate The interference of the signal on the first grid to the second active layer can be shielded, so that both transistors can work normally and effectively, and the reliability and stability of the display device are improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] With the development of technology, the types of displays also increase, including, for example, liquid crystal displays, electroluminescent displays, and the like. Among them, in order to enable the display to realize the display function, it generally includes a driving circuit, which can include multiple transistors; in order to meet different requirements, when setting the active layer of the transistor, silicon-based materials, such as low-temperature polysilicon, or Metal oxide materials such as indium gallium zinc oxide may also be used. [0003] If the driver circuit includes silicon-based transistors and metal oxide transistors, due to the manufacturing process, silicon-based transistors are usually fabricated on the substrate first, and then metal oxide transistors are fabricated, and the two trans...
