Abstract:
This liquid crystal display device allows outputs from RS-FF circuits (401 to 409) and switch circuits (411 to 419), which function as a shift register, to be provided as scanning signals that are selectively activated during odd and even scanning line selection periods, by simply changing the potential of an enable signal (EN) (i.e., by simply providing an EN signal line), which achieves interlacing drive that allows a reduction in the number of polarity inversions, thereby making it possible to reduce power consumption and a wiring area for control lines and achieve simple control which allows circuit simplification, resulting in a reduced frame area and a display panel which is compact as a whole.
