1. A scan signal driving unit comprising:
a plurality of stages configured to sequentially output scan signals;
first clock lines to which first clock signals are applied;
second clock lines to which second clock signals are applied; and
first connection lines configured to connect the plurality of stages and the first clock lines,
wherein:
the first connection lines extend in a first direction, and the first clock lines and the second clock lines extend in a second direction crossing the first direction;
each of the first clock lines includes a (1-1)-th metal pattern and a (1-2)-th metal pattern disposed on the (1-1)-th metal pattern;
each of the second clock lines includes a (2-1)-th metal pattern disposed on the same layer as one of the (1-1)-th metal pattern and the (1-2)-th metal pattern;
the (1-1)-th metal pattern and the (1-2)-th metal pattern are disposed on the first connection lines;
a width of the (1-1)-th metal pattern in a first area overlapping the first connection lines is less than a width of the (1-1)-th metal pattern in a second area not overlapping the first connection lines; and
a width of the (1-2)-th metal pattern in the first area is same as a width of the (1-2)-th metal pattern in the second area.
