摘要: A display substrate and a display device. The display substrate includes a base substrate and a plurality of sub-pixels on the base substrate. Each sub-pixels includes a pixel circuit. The plurality of sub-pixels include a first sub-pixel. The compensation sub-circuit of the first sub-pixel includes a first electrode, a second electrode, and a connection portion between the first electrode and the second electrode. The first drive electrode of the light-emitting element of the first sub-pixel includes a first main body portion including a first side parallel to a certain direction, and a first protruding portion protruding from the first side of the first main body portion. The first protruding portion at least partially overlaps with the connection portion of the compensation sub-circuit of the first sub-pixel in a direction perpendicular to the base substrate. The light-emitting element of the first sub-pixel is configured to emit green light.

摘要: A display panel and a display apparatus. The display panel includes a base layer, a pixel defining layer, red pixels, green pixels, blue pixels, and spacers. The pixel defining layer is on the base layer. The pixel defining layer is formed with a plurality of openings. The red pixels, the green pixels, and the blue pixels are on the base layer. The red pixels, the green pixels, and the blue pixels each are corresponding to one of the openings. The spacers are on the pixel defining layer. The spacers each are between the green pixel and blue pixel adjacent to each other.

摘要: A display substrate includes a scanning driving circuit arranged on a base substrate. The scanning driving circuit includes a plurality of shift register units and a first voltage signal line extending in a first direction. At least one shift register unit includes an output capacitor and a first transistor, a first electrode thereof is coupled to the first voltage signal line, and a second electrode thereof is coupled to an electrode plate of the output capacitor. A maximum distance between an orthogonal projection of the first electrode/second electrode of the first transistor onto the base substrate and an orthogonal projection of the first voltage signal line/the electrode plate of the output capacitor onto the base substrate is smaller than a first/second predetermined distance in a second direction, and the first direction intersects the second direction.
