    Abstract: 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.

    Abstract: A display device includes an initialization voltage line to which an initialization voltage is applied, a first driving voltage line to which a first driving voltage is applied, and a pixel connected to the initialization voltage line and the first driving voltage line. The pixel includes a first transistor to control a driving current flowing between a first electrode and a second electrode according to a voltage applied to a first node, a light emitting element between the first transistor and the first driving voltage line, and a first capacitor between the first node and the initialization voltage line. During an initialization period in which the light emitting element is initialized, the initialization voltage is changed from a first level voltage to a second level voltage lower than the first level voltage and the first driving voltage is changed from a first high-level voltage to a first low-level voltage.
