Abstract: The present disclosure provides a device for manufacturing metal lines and a method of manufacturing metal lines. The device for manufacturing metal lines includes a metal line forming component and a metal line dissolving component. The metal line forming component forms the first metal line from the first solution, then the metal line dissolving component dissolves a portion of the first metal line with a second solution to form a second metal line. Therefore, a size of the first metal line is reduced to form the second metal line, thereby solving a problem of too-large widths between metal lines in conventional display panels.
