Summary:The present invention relates to a display panel and a manufacturing method thereof. The display panel includes: a touch electrode provided to supply a common voltage; a first signal line connected to the touch electrode and provided to supply the common voltage applied by a driving IC to the touch electrode; a plurality of dummy lines provided to be connected to the touch electrode; and a switching transistor provided to supply the common voltage to a second signal line by being switched by an applied VCOM enable signal, wherein the second signal line is configured to supply the common voltage to the touch electrode. Accordingly, it is possible to solve a common voltage imbalance occurring in the touch electrode by including the plurality of signal lines providing the common voltage to the touch electrode. 본 발명은 전극을 통하여 공통 전압이 공급되도록 구성된 터치 전극; 상기 터치 전극과 접속되고, 구동 IC에 의해 인가된 상기 공통 전압을 상기 터치 전극으로 제공하도록 구성된 제1 신호 라인; 상기 터치 전극과 접속되도록 구성된 복수의 더미 라인; 및 인가되는 VCOM 인에이블 신호에 의해 스위칭 되어 제2 신호 라인에 상기 공통 전압을 공급하도록 구성된 스위칭 트랜지스터를 포함하고, 상기 제2 신호 라인은 상기 공통 전압을 상기 터치 전극으로 제공하도록 구성된, 표시 패널 및 그의 제조방법에 관한 것이다.
