Abstract
PURPOSE: To obtain the polarizer suited for improving the display effect of the TN- type liquid crystal element in particular, by forming the polarizing layer composed of dyes on the one side of a uniaxially oriented polyvinyl-alcohol-base (PVA) film and the polarizing layer composed of iodine on the other side.
CONSTITUTION: The one side of the PVA film is beforehand subjected to resist treatment and is dyed by using dichromatic dyes, particularly the direct dyes such as of the formula of linear molecular structure having the functional groups making hydrogen bond to the functional groups of PVA at the end parts. Thence, the film is uniaxially oriented, after which the dyed surface is subjected to resist treatment and in the stretched state, I2 is impregnated in the other side. Here, the use of the water-soluble stilbene-base compound (KayaphorFconc) or the like having absorption in the near ultraviolet part and having the fluorescent group emitting blue fluorescence at the time of dyeing makes the display bright and easier to use because of the action to efficiently absorb ultraviolet rays and converting the energy of ultraviolet rays to visible rays and gives high-quality feel because it eliminates yellowing. In this way, the polarizer of good light resistance is obtained.
