Abstract: A touch display panel includes: a base substrate, including a display area and a peripheral area on at least one side of the display area; pixel units in the display area, including a pixel driving circuit and a light-emitting element electrically connected to each other; touch electrodes in the display area; a touch wire electrically connected to at least one touch electrode, at least part of which extends to the peripheral area; a touch lead in the peripheral area, where the touch lead and the touch wire are in different conductive layers; and a contact groove in the peripheral area, where the touch wire and the touch lead are in contact in the contact groove, where the touch wire has a first touch wire portion in the contact groove, and the first touch wire portion extends obliquely with respect to an upper surface of the base substrate.

Abstract: A display substrate and a display device. The display substrate includes a base, an insulating layer, a crack barrier structure, and a signal line. The crack barrier structure is located in a peripheral area, and at least a part of an orthographic projection of the crack barrier structure onto the base extends in an extension direction of a boundary of a display area. The crack barrier structure includes: a groove structure and a blocking portion, the groove structure is in the insulating layer, and a part of the blocking portion is located in the groove structure. The signal line is located at the peripheral area, and includes a top surface facing away from the base, and a side surface located between the top surface and the base, and at least a part of the side surface away from the display area is between the blocking portion and the groove structure.

Abstract: A display substrate and a display device are provided. The display substrate includes: a plurality of sub-pixels; a first electrode layer including a plurality of anode structures; and a pixel definition layer located on a side of the first electrode layer away from the base substrate and including a plurality of openings. For at least some sub-pixels, an orthographic projection of the opening of each sub-pixel falls into that of the anode structure of the sub-pixel on the base substrate, a figure of the orthographic projection of the opening of each sub-pixel has a different shape from a figure of the orthographic projection of the anode structure of the sub-pixel on the base substrate. The figure of the orthographic projection of the anode structure of each sub-pixel has more symmetry axis than the figure of the orthographic projection of the opening of the sub-pixel on the base substrate.
