1. A method for manufacturing a display panel, comprising steps of:
a step S10 of providing a substrate and forming an array driving layer and a binding terminal on the substrate, wherein the array driving layer is correspondingly formed in a display area, and the binding terminal is correspondingly formed in a non-display area;
a step S20 of forming a passivation layer on the array driving layer and the bonding terminal and forming a first through hole in the passivation layer, wherein the first through hole exposes the bonding terminal;
a step S30 of forming a covering layer on the passivation layer, wherein a material of the covering layer comprises molybdenum titanium alloy or titanium;
a step S40 of forming an electrode layer on the covering layer; and
a step S50 of applying a half-tone mask to perform a patterning process on the covering layer and the electrode layer, so that the covering layer forms a first covering portion and a second covering portion, wherein the first covering portion is connected to the binding terminal through the first through hole, the second covering portion is correspondingly disposed on the array driving layer, a second electrode portion is formed by the electrode layer, and the second electrode portion is correspondingly formed on the second covering portion.
