We have designed high performance flexible prism light-guide plate (LGP) in 5 inch TFT-LCD for mobile applications. We adopted novel material such as methacrylate and butyl acrylate mixture, as it called KURARITY. It has good flexibility by addition of butyl acrylate. And it has also good transmissivity because methacrylate is a major compound. Then, we achieved good test result to embody high brightness and flexible BLU in case of LGP of base and upper surface with 5 inch, thickness 1.5mm adding prism construct, it is superior brightness improvement than previous flexible LGP. It shows significant improvement than previous printing form about some 5% and in this course to flexible embody actual material it succeeded prism LGP production by 5 inch injection form process.
