摘要： A scan signal driving unit capable of reducing the RC delay of scan control lines in an ultra-high resolution display, such as 8K UHD. The scan signal driving unit includes a plurality of stages configured to sequentially output scan signals, first clock lines to which first clock signals are applied, and second clock lines to which second clock signals are applied. 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.
