Further, the third refractive index is greater than the second and fourth refractive indexes, the second refractive index is greater than the first refractive index, and the fourth refractive index is greater than the fifth refractive index.11-25-2010
20090004407METHOD AND APPARATUS FOR FABRICATING LIQUID CRYSTAL DISPLAY DEVICE AND SUBSTRATE BASE MATERIAL FOR LIQUID CRYSTAL DISPLAY DEVICE - A plurality of liquid crystal cells are formed by encapsulating pieces of liquid crystal material with in a plurality of first sealing members, respectively, between a pair of flexible substrate base materials. Only respective parts of the pair of substrate base materials are contained inside a vacuum container, and the liquid crystal cells are formed inside the vacuum container reduced in pressure.01-01-2009
