<P>PROBLEM TO BE SOLVED: To provide an optical reflection material superior in flexibility and superior in workability and processability when assembled and processed to a planar light source, by improving intensity of the planar light source without increasing the number of parts when assembled to the planar light source. <P>SOLUTION: At least two white plastic films 2 are partially adhered and laminated while holding a space 3. The white plastic film 2 is partially adhered and laminated by an adhesion layer 4 formed partially on the surface of the white plastic film 2 or by the adhesion layer partially having a projection part formed on the surface of the plastic film 2 while holding the space 3. Consequently, optical reflectance can be increased efficiently. <P>COPYRIGHT: (C)2003,JPO |
