I'm taking it. Figure 1 shows that if the ratio is small, the thermal stability is low. Specifically, domains occur as uneven distribution. In addition, it is easy to swell IT'8 (if + i4 wetness is "&t"), but this occurs because there is insufficient crosslinking of polyvinyl alcohol. , if it decreases by 1%, it is unfavorable, and if the ratio of Tt(oR)4/polyvinyl alcohol is less than 05, it is unfavorable.On the other hand, if
As the positive ratio increases, the l+ resistance value of the display element decreases. This is the excess T1(0n)4 IQ'r product (-
This is because the impurities in the liquid crystal are more
