Polarizing optical microscopy photographs of the (a) POSS-filled LC test cell and (b) LC test cell. Those cells were assembled by two nontreated ITO-glass substrates and placed between crossed polarizers.
The cell structures of (a) a POSS-filled HAN cell containing only one homogeneous alignment layer, (b) a conventional HAN cell, and (c) a LC cell containing only one homogeneous alignment layer and without using vertical alignment layer.
(a) Voltage-dependent transmission curves and (b) phase changes of test cell 1, test cell 2, and test cell 3.
(a) Rising time and (b) falling time of test cell 1, test cell 2, and POSS-filled HAN cell.
Pretilt angles of POSS-filled LC test cells at various cell gaps.
