A pixel structure. The pixel structure includes a base substrate; an insulating island on the base substrate; a light emitting element on a side of the insulating island away from the base substrate; an insulating layer on the base substrate and surrounding the insulating island, the insulating layer spaced apart from the insulating island by a groove; and a reflective layer on a lateral side of the insulating layer surrounding a periphery of the light emitting element, and configured to reflect light laterally emitted from the light emitting element to exit from a light emitting surface of the pixel structure. The insulating layer has a height relative to a main surface of the base substrate greater than a height of the insulating island relative to the main surface of the base substrate. The reflective layer is in direct contact with the base substrate in the groove.
