WAVELENGTH SPLITTING DEVICE, PLANE-TYPE LIGHTING DEVICE USING SAME, AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME |
摘要 |
A wavelength separator is provided with a reflective color filter arranged to intersect with an optical path of light emerging from a principal surface of a light guide plate, and a recycle portion arranged at a side of the light guide plate opposite to the reflective color filter. Out of light incident on the light guide plate, light reflected by the reflective color filter is returned to the reflected color filter again by being reflected by the recycle portion via the light guide plate. |
