Publication number: 20230142449Abstract: A touch-control display panel and manufacturing method therefor, and a display device thereof, relating to the technical field of display. The touch-control display panel comprises: a driving backplane (11), a light-emitting component (12), an encapsulation layer (13), and a touch-control layer (14). A touch-control insulating layer (142) in the touch-control layer (14) covers the encapsulation layer (13), and the smallest gap (L1) between the border of the driving backplane (11) and at least part of the border of the touch-control insulating layer (142) most proximal to the border of the driving backplane (11) is smaller than the smallest gap (L2) between the border of the driving backplane (11) and the border of the encapsulation layer (13) most proximal to the border of the driving backplane (11). Thus damage to the encapsulation layer (13) during the process of forming the touch-control insulating layer (142) can be avoided, thereby increasing the encapsulating effect of the encapsulation layer (13).Type: ApplicationFiled: May 6, 2021Publication date: May 11, 2023Inventors: Zhiwen CHU, Bo ZHANG, Hongwei MA, Qian MA, Tingliang LIU
