摘要： A connector, a display screen and a method for manufacturing the display screen are provided. The connector includes a substrate, and a conductor structure arranged on the substrate. One end of the conductor structure is connected to a data signal line on a display panel, and the other end of the conductor structure is connected to a driver integrated circuit IC arranged on a non-display side of the display panel. A target surface, away from the substrate, of the conductor structure is uneven. The connector reduces the probability of the conductor structure breaking under the stress of the substrate, thereby guaranteeing the good display effect of the display screen.
