ABSTRACT:
There is provided a spread illuminating apparatus to ensure excellent light conductivity. A cover is integrally provided over a transparent substrate sandwiching a fluid (cushioning material) of a gel, liquid, or gaseous substance. With this structure, dust generated in assembly process is prohibited from getting on the transparent substrate, and even when other members or an assembly machine hit and bend the cover during the assembly process, the bending is absorbed by the fluid, and a light reflection pattern formed on the transparent substrate is protected against damages, whereby excellent light conductivity can be maintained.
