    摘要： Disclosed is a display substrate, comprising a plurality of conductive layers, which comprise a plurality of data lines, a plurality of connection lines and a plurality of fan-out lines. The connection lines cross over at least one data line and are insulated from the crossed data line. First fan-out lines are electrically connected to the connection lines, and second fan-out lines are electrically connected to the ends of second data lines that are close to a fan-out area. Each first fan-out line comprises an adapter line. The fan-out area comprises a first fan-out area and a second fan-out area, and the adapter lines are located in the second fan-out area. The adapter lines are located on different conductive layers from the plurality of second fan-out lines, and cross over at least one second fan-out line, so that the arrangement sequence, in a first direction, of the ends of the plurality of fan-out lines that are away from a display area is the same as the arrangement sequence, in the first direction, of the plurality of data lines. Each adapter line comprises a main body portion and two connection ends, wherein the main body portion is located on the sides of the two connection ends that are close to the display area.

    摘要： This invention discloses a display panel (100), a display device (10), and a method for manufacturing the display panel (100). A substrate (200), an anode (300), a pixel defining layer (400), a light-emitting layer (500), and a cathode (600) are arranged in sequence. The cathode (600) covers the light-emitting layer (500) and the pixel defining layer (400). The filter layer (700) is disposed on a side of the cathode (600) facing away from the substrate (200). The second light-emitting region (520) corresponds to the blue color filter (730). The second light-emitting region (520) includes a blue light-emitting layer (521) made of a blue light emitting material.
