ABSTRACT:
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.
