Claims20
An array substrate, comprising:
- a substrate, the substrate comprising a package area;
- a metal layer located on the substrate;
- a protective layer, which is etched to only retain the protective layer on the metal layer in the package area;
- and
- a frit coated on the package area and located on the protective layer,
- wherein the substrate comprises a display area and a non-display area, the metal layer comprises a plurality of layers formed in the non-display area, dielectric layers are disposed between the plurality of layers, the plurality of layers comprise a bottom metal layer, a middle metal layer and a top metal layer which are separated from each other by the dielectric layers, and the top metal layer in the package area is directly coated with the frit.
