Abstract
PURPOSE: To reflect efficiently illumination light without deformation by external force by constituting a single-body reflecting plate by integrally forming a reflection part and a suppor part by pressure-welding or bonding.
CONSTITUTION: On the reverse surface of liquid-crystal 1, photoconductor 2 for supplying illumination light from light source 4 to liquid-crystal cell 1 is arranged and on its lower surface side, reflecting plate 7 is also arranged which reflects external light and the illumination light to the display part. Reflecting plate 7 is formed integrally of reflection part 5 of a silver sheet, etc., of 0.05mm in thickness for the efficient reflection of the illumination light and support part 6 of a phosphor- bronze sheet, etc., of 0.1mm in thickness for the protection from deformation due to external force by pressure-welding. Consequently, the deformation due to external force during work and handling can be prevented, and the illumination light is reflected efficiently, thereby making display easy to see.
