ILLUMINATING DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE:To improve brightness and efficiency by reducing or preventing the leakage of light leaking to the outside from a light transmission body. CONSTITUTION:Plural rough surface reflection parts 17 reflecting the light from a pair of fluorescent lamps 14a and 14b by rough surfaces and transmitting it to the light exiting surface 13a of the light transmission body 13 are formed on an opposed surface opposed to the light exiting surface 13a. The density of the mutual reflection parts 17 is set so that the density may be made higher and higher as they go away from a pair of lamps 14a and 14b.
