ABSTRACT:
A scanning circuit has L scan control signal lines to which scan control signals differing from each other are supplied, and x pulse generating circuits each of which outputs a pulse signal based on a logical computation on scan control signals supplied from m signal lines, combinations of the m signal lines differing from each other. The scan control signal lines are divided into m groups so that the m groups respectively correspond to m groups of signals supplied to the scan control signal lines. Each of at least m-1 groups among the m groups is composed of three to four scan control signals differing in phases. One scan control signal is selected from each of the m scan control signal line groups so as to constitute each combination of the m scan control signal lines for sending the scan control signals to each pulse generating circuit.
