The invention discloses a wide-angle light-polarizing inner lampshade structure and belongs to the technical field of automobile lamps. The wide-angle light-polarizing inner lampshade structure comprises an inner lampshade, wherein the inner lampshade comprises multiple optical units and a connecting column, each optical unit comprises a condenser, a light-polarizing optical face and a diffusing pattern face. The condenser is located at the light inlet end of the inner lampshade and used for converging light. The connecting column is used for connecting the light inlet end and the light outletend of the inner lampshade. The light-polarizing optical face and the diffusing pattern face are located at the light outlet end of the inner lampshade. The light-polarizing optical face is mainly divided into an oblique plane having a larger dip angle and an oblique plane having a smaller dip angle, the oblique plane having the larger dip angle mainly plays a refraction effect to achieve small-angle light polarization,
