Abstract: A display panel including a substrate; a light-emitting element; and a light-shielding layer. The light-emitting element is located at a side of the substrate and includes a primary light-emitting element and an auxiliary light-emitting element. The light-shielding layer is located at a side of the light-emitting element facing away from the substrate and includes a first opening corresponding to the primary light-emitting element. The auxiliary light-emitting element is arranged at a periphery of the primary light-emitting element.

Abstract: A field lens and a display device are provided. The field lens includes a lens body and an optical structure. The lens body includes at least two layers of gratings. Along a direction perpendicular to a plane where the lens body is located, the lens body includes a first side and a second side. The optical structure is located on a side of at least one grating layer close to the second side. The optical structure is used to block at least part of the visible light from being incident on one side of the lens body and/or to block at least part of the visible light from being emitted toward the second side of the lens body after being reflected by the gratings.

Abstract: A display panel including a substrate, a light-emitting element layer, and a light-shielding layer. The light-shielding layer is arranged at a side of the light-emitting element layer facing away from the substrate. In the light-emitting element layer, an auxiliary light-emitting element is arranged at a periphery of the primary light-emitting element. The light-shielding layer includes a first opening corresponding to the primary light-emitting element and a light-shielding part covering the auxiliary light-emitting element. When both the primary light-emitting element and the auxiliary light-emitting element emit light, the viewer at a large viewing angle sees light emitted by the primary light-emitting element and interfering light emitted by the auxiliary light-emitting element; and when the primary light-emitting element emits light and the auxiliary light-emitting element does not emit light, the viewer only sees the light emitted by the primary light-emitting element.
