| Research Abstract |
The diffusion seat for liquid crystal display was made by using new laser microprocessing technology which was developed by our laboratory. This technique using nanosecond pulse UV laser is simple compared with the conventional production technology. By using this technique, we were able to make reproducible small holes in transparent resin sheets of polyethylene terephtalate (PET) and polyphenylene sulfide (PPS). The resin sheets having through holes with narrow pitch function as the diffusion seat for liquid crystal display.
