The present invention provides a display driver circuit having a simple configuration
due to a decrease in the number of voltage levels and capable of preventing deterioration
of contrast ratio in display drive by using MLS, an electro-optical device, and
a display drive method. First to fourth bits of grayscale data corresponding to
a display pattern for three lines are supplied to each ROM. The ROMs decode and
output 4MLS operation results for a display pattern defined by the first to fourth
bits of the grayscale data and a dummy display-pattern corresponding to the display
pattern based on orthogonal functions defined by combinations of a scan pattern
and a dummy scan pattern of a virtual electrode based on a field signal.
