Display device

A display device, comprising:

• a plurality of pixel circuit rows;
• a plurality of selection lines connected to the plurality of pixel circuit rows;
• and
• a shift register including a plurality of linked shift register units,
• wherein the plurality of shift register units output sequential selection pulses to the plurality of selection lines,
• wherein each of the plurality of shift register units outputs one of the selection pulses to a corresponding selection line among the plurality of selection lines,
• wherein each of the shift register units includes a plurality of thin film transistors of a first conductivity type that are connected in parallel, and that, during an ON state, connect the corresponding selection lines to a fixed potential wiring line for applying a non-selection level for the one of the selection pulses,
• wherein, during each frame period, the plurality of thin film transistors are turned ON/OFF by clock signals in different phases, and
• wherein the duty cycle of the ON period of each of the plurality of thin film transistors during each said frame period is 12.5% or less.
