Zusammenfassung:The present invention provides a data driving part and a display device including the same that improve the transmission characteristics of a signal by reducing the branch length of the data driving part. According to the present invention, the data driving part includes a plurality of data driving circuits and a plurality of EPI lines arranged on a printed circuit board and connected to the plurality of data driving circuits in a multi-drop manner. The EPI line is composed of a plurality of branches connected to one main line and the plurality of data driving circuits, respectively. The main line includes a plurality of coupling parts electrically connected to the plurality of branches and a connection part connecting the plurality of coupling parts. The coupling parts are disposed more adjacent to the plurality of data driving circuits than the connection part. 본 발명은 데이터구동부의 브랜치 길이를 감소시킴으로써, 신호의 전송특성을 향상시키는 데이터구동부 및 이를 포함하는 표시장치를 제공하는 데 있다. 본 발명에 따른 데이터구동부는 다수의 데이터구동회로 및 인쇄회로기판상에 배치되며, 멀티드랍(multi-drop)방식으로 상기 다수의 데이터구동회로와 연결되는 다수의 EPI라인을 포함하고, 상기 EPI라인은 하나의 메인라인과 다수의 데이터구동회로와 각각 연결되는 다수의 브랜치로 구성되고, 상기 메인라인은 다수의 브랜치와 전기적으로 접속되는 다수의 접속부와 상기 다수의 접속부를 연결하는 연결부로 구성되고, 상기 접속부는 상기 연결부보다 상기 다수의 데이터구동회로에 인접되도록 배치된다.
