Abstract:
A display device comprising:a display panel having a display screen constructed by a plurality of signal lines and a plurality of switching lines arranged in a matrix, a plurality of switching elements electrically connected to said signal lines and scanning lines, and pixel electrodes connected to said switching elements;a scanning circuit section for supplying scanning signals to said scanning lines, anda scanning control circuit section for flexibly changing the location of a display area by controlling an n-bit input numeral signal, n being a positive integer equal to or greater than 2, and for supplying the n-bit input numeral signal and an inverted replica of the input numeral signal to said scanning circuit section, wherein said scanning circuit section includes: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, fewer in number than said scanning lines, for responding to combinations of the input numeral signal and the inverted replica of the input numeral signal, andoutput distributing means for assigning an output from one logic circuit section to at least two scanning lines.
