ABSTRACT:
A light source device for preventing a light guide plate from being discolored due to a light supplied by a lamp is disclosed. At least one masking film that is made of a transition metal oxide is disposed in a pathway of the light that is emitted by the lamp and transmitted to a display unit to display images in order to cut off ultraviolet rays having particular wavelengths capable of discoloring the light guide plate. Accordingly, it is possible to prevent the light guide plate, which is made of polyolefin resin composition to make it lightweight, from discoloring in yellow.
