A display panel, a crack detection method and a display device are provided. The display panel includes a substrate, a signal wiring disposed over the substrate, and a test wiring insulated from the signal wiring and disposed on a side of the signal wiring facing away from the substrate. An orthographic projection of the test wiring on the substrate overlaps an orthographic projection of the signal wiring on the substrate. The display panel also includes a first test terminal disposed over the substrate and electrically connected with an end of the test wiring, and a second test terminal disposed over the substrate and electrically connected with another end of the test wiring.

Display panel and crack detection method, and display device

Disclosed are a manufacturing method of a display panel, a display panel and a display device. The manufacturing method includes the following steps: providing a base substrate; forming a planarization layer on a side of the base substrate; forming a first film layer on a side of the planarization layer facing away from the base substrate; forming an anode via penetrating through the first film layer and the planarization layer; forming an anode layer on a side of the first film layer facing away from the base substrate; patterning the anode layer to form a first opening on the anode layer; and after patterning the anode layer, patterning the first film layer to form a second opening on the first film layer. A material of the first film layer includes a non-metallic material.

Manufacturing method of display panel, display panel and display device

A display panel, a method for fabrication a display panel, and a display device are provided. The display panel includes a display area, and a non-display area surrounding the display area and a first bezel area being in the non-display area; a substrate; a wiring layer, disposed on the substrate and in the non-display area, and including at least one first lead and at least one second lead, and at least a partial line segment of the at least one first lead and at least a partial line segment of the at least one second lead are disposed in the first bezel area; a polarizer disposed on a side of the wiring layer away from the substrate; and a first light-emitting layer, at least distributed in the first bezel area and, along a direction perpendicular to the substrate, disposed between the substrate and the wiring layer.

Display panel having bezel area including light-emitting layer overlapping wiring leads

The present disclosure discloses a display panel, a manufacturing method thereof and a display device. By arranging positions of first transmission pads and second transmission pads, and setting areas of first film layers in the first transmission pads to be less than those of second film layers, when the first transmission pads and the second transmission pads are disposed oppositely, fully-opened openings are formed between the two pads, so that it is convenient to fill spaces between the first transmission pads and the second transmission pads with conductive components to allow the first transmission pads be electrically connected with the second transmission pads through the conductive components, guaranteeing an effective electrical connection between the first transmission pads and the second transmission pads and then ensuring signal transmission via first wires and second wires through the first transmission pads and the second transmission pads.

Display panel with layered transmission pads in non-display area, manufacturing method thereof and display device

Display panel and display device are provided. The display panel includes a display region; a non-display region; and a notch. Data lines are disposed in the display region. An edge of the display panel recesses toward the display region to form the notch. The display region includes a first display region and second display regions. The notch and the first display regions are disposed between two second display regions in the first direction and are adjacent in the second direction. The data lines include first data lines in each of the second display regions separated by the notch. Connection lines are disposed surrounding the at least one notch, and each connection line connects two of the first data lines in a same column and on two sides of the notch At least a portion of the connection lines includes first segments disposed in the first display region.
