Abstract
Embodiments of the present invention provide a touch substrate, a manufacturing method thereof and a touch display panel to solve the problem in the prior art that leads connected with a touch unit excessively occupy the peripheral area of an active area. According to the touch substrate, the manufacturing method thereof and the touch display panel provided by embodiments of the present invention, the peripheral area of the active area occupied by the leads is reduced as the first or second leads are provided within the active area, so that the design of narrow bezel for touch screen can be achieved.
Claims19
