Abstract

Abstract A liquid crystal display panel to electrically and mechanically be connected to a substrate of an electronic apparatus comprises a liquid crystal display, a terminal connection member, and a metal plate such as a stainless. The terminal connection member is provided for electrically and mechanically coupling the liquid crystal display with the substrate of the electronic apparatus at a terminal connection portion. The metal plate is positioned at the terminal connection portion to shield a hard and fragile substrate of the liquid crystal display.
