(54) DISPLAY SUBSTRATE AND DISPLAY DEVICE


(57) 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.
