<p>PURPOSE:To miniaturize a display device and to lower the cost by simplifying constitution of a driving circuit in a liquid crystal display device. CONSTITUTION:The liquid crystal display device is provided with the liquid crystal display panel LC and the driving circuit DD which drives and controls the liquid crystal panel LC, wherein, the driving circuit DD is provided with the first plural constitution circuits M21-M24 corresponding to numbers of data lines of the liquid crystal display panel LC, the second constitution circuits DAC which are provided in every prescribed numbers of the first constitution circuits M21-M24, the selecting means MPX which successively selects output of the first constitution circuit M21-M24 and supplies it to the second constitution circuit, and switching means S1-S4 which successively switches output of the second constitution circuit DAC, also the second constitution circuit DAC is constituted so as to supply the output to each data lines in time sharing way.</p> |
