摘要: This invention relates to a liquid crystal display apparatus and particularly to a liquid crystal display apparatus based on a liquid crystal light emitter actuated by the heat from a laser beam.A liquid crystal display apparatus according to this invention is formed such that an energy beam is irradiated onto the arrays of smectic liquid crystal particles having polarities equivalent in energy directions and opposite to each other in dipole moments of the particles and applied with a voltage, which is too low to switch the arrays to each other to provide the display.Consequently, according to the liquid crystal display apparatus of this invention, the writing speed of the display can be improved significantly and a high contrast of the display can be presented.
