Reverse Twisted Nematic (RTN) LCDs, which use the liquid crystalline materials twisting opposite
from the one for usual TN-LCDs, have been reported to be driven by low driving voltage. RTN
molecular arrangement can be formed by applying electric voltage to the splay twist state. The
formed RTN state can be maintained tentatively, however, returns into splay twist state gradually
without applied voltage. For stabilisation of RTN state, polymer matrix formation in the whole LC
region was effective but caused driving voltage to increase. The usage of high pretilt angle
alignment layers and the introduction of wall structures into LC layer were proposed. However,
these methods had the defects like low transmittance and the complicated procedures, respectively. In this article, it is reported that RTN state can be stabilised by the polymer matrix formation
just in the vicinity of alignment layer. This phenomenon is considered to be the first successful
example in which the LC molecular arrangement twisting opposite from the intrinsic twist direction can be stabilised by fixing the structure near alignment layer surface. By this method, the
usage of RTN-LCDs of low driving voltage can be realised
