Metal structure and method for fabricating same and display panel using same

A display panel, comprising:

• a first substrate, having an outer surface, an inner surface, and a first side edge connecting the outer surface and the inner surface of the first substrate, wherein the outer surface serves as a display surface of the display panel;
• a second substrate, having an outer surface, an inner surface, and a second side edge connecting the outer surface and the inner surface of the second substrate, wherein the inner surface of the second substrate is opposite to the inner surface of the first substrate, the first side edge and the second side edge are located on a same side of the display panel, and the first side edge is substantially aligned with or longer than the second side edge;
• a display medium layer, disposed between the first substrate and the second substrate;
• a patterned molybdenum tantalum oxide layer, disposed on the inner surface of the first substrate;
• and
• a patterned metal layer, disposed between the patterned molybdenum tantalum oxide layer and the inner surface of the second substrate, wherein the patterned molybdenum tantalum oxide layer comprises 2 to 12 atomic percent of tantalum, and both of an atomic percent of molybdenum and an atomic percent of oxygen are greater than the atomic percent of tantalum.
