SUBSTRATE FOR REFLECTOR BODY, REFLECTOR BODY USING THE SAME, SIDE LIGHT TYPE BACK LIGHT DEVICE, AND LIQUID CRYSTAL DISPLAY

PROBLEM TO BE SOLVED: To provide a side light type back light device in which the luminance is higher than that of the conventional type and the unevenness of luminance hardly occurs, a substrate for a reflector body having a surface shape necessary for the back light device, and a highly durable re...

Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a side light type back light device in which the luminance is higher than that of the conventional type and the unevenness of luminance hardly occurs, a substrate for a reflector body having a surface shape necessary for the back light device, and a highly durable reflector body using the substrate, in which a warpage due to heat is suppressed. SOLUTION: A substrate, on which a projected face on one side and a flat face on the other side are formed in a unit preferably by a coextrusion method, is used as a reflection body used for the lower face of a light guide plate of a surface light source device, and a reflection body, obtained by successively laminating preferably an under layer, a metallic layer which is composed essentially of silver and a protective layer is used as a reflection layer on the flat face of the substrate, by directing the substrate side upward.
