Abstract
PURPOSE: To obtain a high-definition image by providing plural liquid crystal light valves and arranging respective picture elements formed on a screen by light transmitted through the valve in a gap between the respective picture elements by another liquid crystal light valve. CONSTITUTION: The optical system is adjusted so that the picture element 4 of a liquid crystal light valve 2 may form the image in the gap of the respective picture elements 3 of the liquid crystal light valve 1 in the case projection is performed by using the light valve 1. Thus, the number of picture elements on the screen is twice as large as that of the light valve, and also the vertical resolution thereof is twice as high as that. Furthermore, the gap between the picture elements hardly exists and the image becomes smooth. An image signal is alternately written in the liquid crystal light valves 1 and 2 in every horizontal scanning period. Then, the selection time of the picture element is twice as long as the case the picture elements having the same number are formed by one light valve, and allowance is obtained in the write of a thin film transistor.
