20140211311 | LIQUID CRYSTAL DISPLAY HAVING IMPROVED WAVELENGTH DISPERSION CHARACTERISTICS - A multilayer optical retardation compensation film having at least one positive C-plate and at least one negative C-plate is used in an LCD device. The multilayer film may have a substantially flat wavelength dispersion curve, or the multilayer film combined with other layers in the LCD device may have a substantially flat wavelength dispersion curve. Polymer films for the positive C-plate may be identified according to their absorbance maxima at certain wavelength ranges. | 07-31-2014 |
