DIFFUSION PLATE, BACKLIGHT UNIT, LIQUID CRYSTAL DISPLAY, METHOD FOR MANUFACTURING DIFFUSION PLATE, AND METHOD FOR ENHANCING COLOR REPRODUCIBILITY

摘要

A light absorption material absorbing a light of a dummy wavelength range or noises is added to a diffusion plate to remove light of an unnecessary wavelength band when using a cold cathode fluorescent lamp ("CCFL") to enhance color reproducibility. Because the light absorption material is simply included in the diffusion plate, a fabrication or development cost can be reduced, and because a production line is not necessary, costs can be saved.
