A pressure-sensitive adhesive layer by direct or transfer method by screen printing is provided on the part surface of the reflecting plate of the white film or the like which substantially corresponds to the lamp and not to face the side surface of the light guide plate, a side light type backlight We want to produce a light guide portion reflection plate. By the pressure-sensitive adhesive layer to the reflector is fixed to the light guide plate such as acrylic plate, further in the state of overlapping diffuser plate on the light guide plate installed in a liquid crystal display plate or the like, a light guide portion of the side light type backlight It makes up the structure. Thus, to bond the double-sided adhesive tape on the reflecting plate, as compared to prior art light guide structure that produced by attaching a reflection plate to the light guide plate, eliminating the double-sided adhesive tape manufacturing process, and laborsaving The aim of cost reduction, it is possible to provide an inexpensive light guide portion structure, thus, also allows cost reduction of the liquid crystal panel or the like.
