Abstract
A pixel structure includes a base substrate and a light emitting element on the base substrate. The light emitting element includes a reflective electrode, a light emitting layer on the reflective electrode, and a substantially transparent electrode on a side of the light emitting layer away from the reflective electrode. The reflective electrode has a reflective ridge configured to reflect light laterally transmitted through the light emitting layer to exit from a light emitting surface of the pixel structure. The reflective ridge has a first concave reflective sidewall extending from a peak of the reflective ridge to a base of the reflective ridge, and a second concave reflective sidewall extending from the peak of the reflective ridge to the base of the reflective ridge. The first concave reflective sidewall faces away from the second concave reflective sidewall.
