The present application discloses an array substrate having a subpixel region and an inter-subpixel region, a display panel and a display apparatus having the same, and a fabricating method thereof. The array substrate includes a plasmonic color filter layer including a plurality of color filter blocks in the subpixel region on a base substrate. Each of the plurality of color filter blocks includes a plurality of plasmonic nanostructures made of a semiconductor material. A first color filter block corresponding to a subpixel of a first color has an arrangement of nanostructures different from that of a second color filter block corresponding to a subpixel of a second color; the second color being different from the first color.
