Auxiliary display structure and optical device

The invention relates to the technical field of image display, and provides an auxiliary display structure and an optical device. The auxiliary display structure is applied to an image field bending space of the optical device. The auxiliary display structure comprises a plurality of light guide units arranged in an array. Each light guide unit is provided with a first light guide surface and a second light guide surface which are oppositely arranged; wherein the first light guide surfaces are spliced to form a main light guide surface of the auxiliary display structure, and the main light guide surface is a curved surface. The optical device comprises a light source and the auxiliary display structure, and light beams emitted by the light source are conducted through the auxiliary display structure. The auxiliary display structure with the curved surface is utilized in light path transmission, the light path difference, caused by the field curvature effect, of pixel fuzzy points around the view field is comp
