Apparatus for arranging spacers at fixed points, liquid crystal device, method of manufacturing liquid crystal device, and electronic apparatus

The invention provides a liquid crystal device that is substantially free from problems, such as deterioration in display contrast by preventing or inhibiting the nonuniformity of the gap between substrates. Since a liquid crystal display device has a structure in which spacers are disposed between a pair of substrates having a liquid crystal layer sandwiched and held therebetween; depressions are formed on the substrate; and the spacers are disposed mainly in the depressions, the gap between the substrates is reliably made more uniform across the surfaces of the substrates. Especially, since the depressions are formed so as to correspond to non-pixel regions, the spacers have less influence on display.
