摘要： A display substrate and a display device are provided. The display substrate includes a first power signal line and a pixel defining layer. The first power signal line includes first power signal sub-lines extending along a first direction and second power signal sub-lines extending along a second direction. The pixel defining layer includes a plurality of openings to define effective light-emitting regions of a plurality of sub-pixels, the plurality of sub-pixels include a sub-pixel pair including two sub-pixels arranged along the second direction, and the sub-pixel pair includes two effective light-emitting sub-regions with an interval therebetween. In a plan view, the first power signal sub-line passes through the interval between the two effective light-emitting sub-regions, at least one second power signal sub-line includes a fracture, and the two effective light-emitting sub-regions are located at the fracture, so that a virtual straight line connecting two ends of a same fracture of the second power signal sub-line passes through the two effective light-emitting sub-regions. Providing the fracture in the second power signal sub-line can reduce the overlap between the two effective light-emitting sub-regions so as to reduce the color deviation of the sub-pixels.

摘要： The present application provides a display substrate and a display apparatus. The display substrate includes a base substrate and a plurality of sub-pixels. A sub-pixel includes a pixel electrode and an effective light-emitting region. The pixel electrode includes a main body portion and a connection portion that are interconnected. Shapes of the main body portion and the effective light-emitting region are the same, and at least partial borders of the main body portion and the pixel electrode coincide. The plurality of sub-pixels at least include a first sub-pixel and a second sub-pixel, and light emitted by the first sub-pixel and the second sub-pixel is the same. The first sub-pixel and the second sub-pixel closest to each other are arranged in a second direction. Areas of orthogonal projections of two pixel electrodes of the first sub-pixel and the second sub-pixel on the base substrate are different. Two orthogonal projections of a connection portion and a main body portion of at least one of the first sub-pixel and the second sub-pixel on a straight line extending in a first direction are at least partially non-overlapped. An orthogonal projection of a pixel electrode of the second sub-pixel on a straight line extending in the second direction is located within an orthogonal projection of a pixel electrode of the first sub-pixel on the same straight line.
