抄録

The lighting-panel (LP) for liquid crystal displays (LCDs), which leads the light from the illuminating light emitting diode (LED) to the front panel, is one of the key parts of personal digital assistants (PDAs) for decreasing the power consumption. We developed a high luminosity LP for LCDs with accurate three dimensional microstructures using synchrotron radiation lithography, and their optical properties were also evaluated using the luminosity distribution measurement. The mean luminosity and the luminescence efficiency were more than 800 cd/m². It is notable, from the simulation results, that the mean luminosity for the LP with trapezoidal cylindrical dots increases to 1.5 times higher than that of the LP with cylindrical dots. Qualitatively, the measured result corresponds well with the simulated results.
