ABSTRACT:
A liquid crystal display panel holding metal fixture that prohibits the flow of solder through a gap at its corner portion when it is soldered to a printed circuit board. The liquid crystal display panel holding metal fixture has bottom and side surfaces that are formed by bending a metal plate cut into a predetermined shape. The bottom surface has corner portions where the cut surfaces of the metal plate are close to each other. The metal plate is plated to impart solder wettability thereto when the metal plate is made of a material having poor solder wettability, and is thereafter cut into the predetermined shape to expose the poor wettability material at the cut portions that prohibit the flow of solder through the gap. Alternatively, the metal plate is made of a material having good solder wettability, and the cut surfaces are subjected to a surface treatment for reducing solder wettability.
