<P>PROBLEM TO BE SOLVED: To provide a scan driving circuit capable of supplying multiple pulse signals to display control lines. <P>SOLUTION: The scan driving circuit includes a shift register section and a logic circuit section. The start of a start pulse of an output signal ST<SB>p+1</SB>of a (p+1)'th shift register is situated between the start and end of a start pulse of the output signal ST<SB>p</SB>of a p'th shift register, and a first enable signal through a Q'th enable signal exist per each in sequence between the start of the start pulse of the output signal ST<SB>p</SB>and the start of the start pulse of the output signal ST<SB>p+1</SB>. The operation of a (p', q)'th NAND circuit is restricted based on period identifying signals, such that the NAND circuit generates scanning signals based only on a signal of a portion of the output signal ST<SB>p'</SB>corresponding to the first start pulse, the signal obtained by inverting the output signal ST<SB>p'+1</SB>, and the q'th enable signal EN<SB>q</SB>. <P>COPYRIGHT: (C)2010,JPO&INPIT |
