ABSTRACT:
A display device comprises a display panel, a scanning circuit section for supplying a scanning signal to scanning lines of the display panel, and a scanning control circuit section for supplying an n-bit (n: 2 or more positive integer) input numeral signal and an inverted replica of the input numeral signal to the scanning circuit section. In the display device, a scanning circuit section comprises an input connection line group having sets of input connection lines for receiving bits of the input numeral signal and bits of the inverted replica of the input numeral signal, a plurality of logic circuit sections, less in number than the scanning lines, for responding to combinations of the input numeral signal and its inverted replica, and an output distributing unit for assigning an output from one logic circuit section to at least two scanning lines. It is, therefore, possible to suppress an increase in the number of connection lines and of the logic circuit sections involving a high definition of a display device and hence to manufacture a display device in a high yield.
