Liquid crystal display apparatus

摘要

A liquid crystal display apparatus wherein laser beams which are modulated in accordance with modulating signals such as video signals are irradiated on a liquid crystal cell for writing the display image or picture on the cell. In the present invention, the laser beams emitted from two laser beam sources are combined at a polarization beam splitter with an angular offset between the respective optical axes equal to DELTA theta , and the picture components corresponding to two scanning lines are simultaneously written into the liquid crystal cell during one scanning period, for increasing the image writing speed.
