摘要： A display assembly includes a display panel and a light adjusting layer disposed on a light-emitting side of the display panel. The display panel has a middle display region and a peripheral display region, and is configured to project light towards an optical device. An orthographic projection of the light adjusting layer on the display panel at least partially overlaps with the peripheral display region. The light adjusting layer is configured to: deflect at least a portion of light emitted to a first region of the optical device and at least a portion of light emitted to an outer side of the optical device among light emitted from the peripheral display region, after passing therethrough; and emit the deflected light to a second region of the optical device. The second region is farther away from a center of the optical device than the first region.
