Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is a U.S. National Phase of International Application No. PCT/CN2021/115477 entitled “DISPLAY SUBSTRATE AND DISPLAY DEVICE,” and filed on Aug. 30, 2021. The entire contents of the above-listed application are hereby incorporated by reference for all purposes. TECHNICAL FIELD The present disclosure relates to the field of display technology, in particular to a display substrate and a display device. BACKGROUND Three-dimensional (3D) application based on ultra-high resolution is the development trend of an existing 3D display technology, but an existing 3D scheme has such technical problems as moire pattern. One of reasons for the moire pattern lies in light-emission discontinuity of pixels. In a conventional pixel design, a source/drain metal line (SD line), e.g., a data line, is linear and non-transparent. When an image is displayed, periodic light shielding regions will appear between the pixels due to a low transmittance of the source/drain metal line, so the pixels emit light discontinuously. In a 3D display state, the moire pattern occurs due to the light-emission discontinuity of pixels.
