Gate driving circuit having a node controller and display device thereof

A display device comprising:

• a display panel including data lines, gate lines, and subpixels;
• a data driving circuit configured to supply a data signal of an input image to the data lines;
• and
• a gate driving circuit configured to supply a gate signal to the gate lines, wherein:
• the gate driving circuit includes a plurality of subordinately connected stages,
• an Nth stage, N being a natural number, includes:
• a node controller configured to control voltages of a first node and a second node according to a set signal and a reset signal;
• and
• a plurality of scan pulse output units configured to receive a plurality of scan clocks, and output each of the scan clocks as a scan pulse according to voltages of the first node and the second node,
• wherein a last scan pulse output unit among the plurality of scan pulse output units further outputs a corresponding scan clock as a scan pulse while receiving a first node voltage of an (N+1)th stage,
• wherein the last scan pulse output unit includes:
• a first pull-up transistor configured to turn on or off based on a voltage of the first node to output a corresponding scan clock to an output terminal;
• and
• a second pull-up transistor configured to turn on or off based on the first node voltage of the (N+1)th stage to output the corresponding scan clock to an output terminal, and
• wherein the first pull-up transistor and the second pull-up transistor are connected in parallel.
