A display substrate and a display device are provided. The display substrate includes a backplane including a plurality of pixel regions; and light emitting units arranged in one-to-one correspondence with the plurality of pixel regions. Each light emitting unit includes light emitting sub-units arranged in a plurality of rows and a plurality of columns, each row of light emitting sub-units includes a plurality of light emitting sub-units arranged along a row direction, each column of light emitting sub-units includes one light emitting sub-unit, and orthographic projections of light emitting regions of two adjacent columns of light emitting sub-units on a first straight line extending along a column direction are not overlapped; and in each light emitting unit, there is no gap between orthographic projections of the light emitting regions of the two adjacent columns of light emitting sub-units on a second straight line extending along the row direction.

Display substrate and display device

A light-emitting diode (LED) chip includes a plurality of epitaxial structures, at least one first electrode, and a plurality of second electrodes. Any two adjacent epitaxial structures of the plurality of epitaxial structures have a gap therebetween. Each epitaxial structure includes a first semiconductor pattern, a light-emitting pattern and a second semiconductor pattern stacked in sequence. First semiconductor patterns in at least two of the plurality of epitaxial structures are connected to each other to form a first semiconductor layer. A first electrode is electrically connected to the first semiconductor layer. Each second electrode is electrically connected to the second semiconductor pattern in at least one of the plurality of epitaxial structures.
