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.

Claims

1. A liquid crystal display panel comprising:

a first substrate plate;

a second substrate plate superimposing said first substrate plate with a first side adjacent said first substrate plate, said first side of said second substrate plate having a terminal connector electrode portion wherein display electrodes disposed between said first and second substrate plates have leads that extend to said terminal connector electrode portion;

sealing means disposed between said first and second substrate plates for providing a sealed volume between said first and second substrate plates;

liquid crystal composition disposed within said sealed volume;

a metal plate laminated to a second side of said second substrate plate, said metal plate superimposing said terminal connector electrode portion for increasing the mechanical strength of said second substrate plate at said terminal connector electrode portion; and
