Classification: CPC H | IPC H

Claim 0:
1. A display panel, comprising:
a substrate;
at least one metal layer disposed on the substrate;
a darkening layer covering the at least one metal layer; and
a light transmissible functional layer covering the darkening layer;
wherein an adhesive force of a photoresist to the light transmissible functional layer is greater than an adhesive force of the photoresist to the darkening layer, and an adhesive force of the light transmissible functional layer to the darkening layer is greater than the adhesive force of the photoresist to the darkening layer;

a material of the light transmissible functional layer comprises a transparent conductive material, silicon nitride, or a metal; and
the display panel further comprises a protecting layer covering the light transmissible functional layer:,
wherein a thickness of the darkening layer ranges from 30 nm to 150 nm and a thickness of the light transmissible functional layer ranges from 10 nm to 70 nm;
wherein the at least one metal layer comprises two layers, one layer of the metal layer is a gate metal layer and the other layer of the metal layer is a source drain metal layer.
