Abstract
A blue-phase liquid crystal display (BP-LCD) with an in-plane switching (IPS)
electrode and etched substrate for generating double-penetrating fringe fields is
proposed. An etching depth of 1–2 $\mu{\hbox{m}}$ helps to lower the operating voltage
by $\sim$30%. This etched IPS BP-LCD also exhibits a wider viewing angle than the
conventional one because of the created multi-domain structures in the etched areas.
Physical mechanisms responsible for the observed phenomena are discussed.
