Patent ID: 7221338

Claim:
A display device comprising: a plurality of pixels, each comprising a light emitting element, the light emitting element comprising an anode, a cathode and an organic compound layer provided therebetween; and a source signal line driver circuit, wherein: said source signal line driver circuit comprises a switching circuit for switching a polarity of an output signal, a polarity of a digital video signal input to said switching circuit is inverted by means of a shift signal to he input into said switching circuit and a resultant digital signal is then input into said plurality of pixels, said switching circuit comprises an inverter, a first analog switch, and a second analog switch, said digital video signal input into said switching circuit is input into an input terminal of said first analog switch through said inverter, said digital video signal input into said switching circuit is input into an input terminal of said second analog switch, said shift signal input into a first control input terminal of said first analog switch and a second control input terminal of said second analog switch, a signal obtained by inverting a polarity of said shift signal is input into a first control input terminal of said second analog switch and a second control input terminal of said first analog switch, and signals output from output terminals of said first analog switch and said second analog switch are output from said switching circuit.
