A method and a structure for a converging-type electron-emission source of a field-emission display are disclosed. A substrate is provided, and a silver paste is used to form a first electrode layer on the substrate by the process such as thick-film photolithography screen-printing. At least one pit is formed in the first electrode layer by etching, for example. A passivation layer is formed on the first electrode layer around the pit. A second electrode layer is formed in the recess by photolithography or electrophoresis, for example. Preferably, the second electrode layer is formed with a top surface lower than a periphery of the pit, such that a converging opening of the second electrode layer is formed over the second electrode layer. The passivation layer is then removed, followed by a step of sintering process.
