Disclosed are an array substrate, a display panel and a display device. The array substrate includes: a base substrate provided with a bonding region for packaging a chip on film, and a first electrode structure, an interlayer dielectric layer, a second electrode structure and a third electrode structure sequentially arranged on the base substrate, the orthographic projections of the first electrode structure, the interlayer dielectric layer, the second electrode structure and the third electrode structure on the base substrate being located in the bonding region. The array substrate further includes protection layers located between the first portion of the second electrode structure and a third electrode and between the second portion of the second electrode structure and the third electrode respectively; and the protection layers cover the side end face of the first portion and the side end face of the second end surface.

Array substrate, display panel and display device

The present invention provides a display panel, a fabricating method thereof and a display device. The display panel comprises a pixel region and a fan-out region, first signal lines and second signal lines are provided to intersect each other in the pixel region, and extend into the fan-out region, respectively, a first insulation layer is provided between the first signal lines and the second signal lines, a second insulation layer is provided on the second signal lines, the second insulation layer comprises at least four layers of structures, and a density of each layer of structure of the second insulation layer decreases gradually along a direction away from the first insulation layer. A size of the via hole formed in the second insulation layer by etching is smaller than that of the via hole formed in the prior art.
