A liquid crystal display apparatus which have a circular polarizer and a
liquid crystal display in a stack. The liquid crystal display has a
chilral nematic liquid crystal layer between substrates, and on the
mutually opposite sides of the substrates, electrodes and aligning layers
are formed. The liquid crystal switches between a planar alignment state
and a focal-conic alignment state depending on the voltage applied
thereto through the electrodes. In a planar state, light reflected by the
electrodes is absorbed by the circular polarizer, and a black display is
made. In a focal-conic state, light reflected by the electrodes passes
through the circular polarizer, and a white display is made. The liquid
crystal is driven by a chain of voltage pulses including a reset step of
resetting the liquid crystal to a homeotropic state, a selection step of
selecting the alignment state of the liquid crystal under zero-volt
application and an evolution step of causing the liquid crystal to evolve
to the selected alignment state.
