Abstract:
A method of forming a metal pattern comprises forming a metal ink layer on a substrate; heating the substrate on which the metal ink layer is formed; forming a protective layer on the metal ink layer; patterning the metal ink layer by allowing a laser irradiated at the upper portion of the substrate to pass through the protective layer; and leaving a metal pattern by removing the protective and metal ink layers. The method of forming a metal pattern layer is provided to prevent a metal ink layer from coming in direct contact with oxygen in the air, moisture and external light by performing a laser patterning process after forming the protective layer on the metal ink layer, thereby improving uniformity when a metal pattern is formed through laser patterning.
