    • The data signal line driving circuit of the present invention is arranged so that data signal line groups, each of which is made up of two data signal lines sequentially disposed, are connected to two video signal lines, each of which allows a two-phased video signal to be forwarded. A shift register SR, a drive switching circuit, and a waveform shaping circuit, that constitute a video signal fetching section, collect the data signal line groups via the two video signal lines as a single block. At this time, the data signal lines are respectively driven so as to fetch the video signal from the video signal lines into the data signal lines of the data signal line groups in each block. Thus, in performing multiphase development, it is possible to provide the data signal line driving circuit which can reduce power consumption in low resolution driving compared with a case of high resolution driving.

    • A data signal line drive circuit is provided with: a shift register belonging to a system, whose stages correspond to respective sampling units for driving odd-number-th data signal lines; and a shift register belonging to another system, whose stages correspond to respective sampling units for driving even-number-th data signal lines. On the occasion of low-resolution mode, only either of the shift registers is operated, and in accordance with the outputs from the respective stages of the shift register which has been operated, timing signals, which are supplied to the sampling units corresponding to the stages of both shift registers, are generated. With this arrangement, even if one of input signals each having different signal line resolution is inputted, a signal line drive circuit which consumes a small amount of electric power can be realized, while it is possible to specify the timings of the operation of signal line drive sections for driving signal lines, in accordance with the input signal.
