Provided is a stereoscopic display device, including: a base member transmitting an incident beam; and a three-dimensional effect forming part on a first surface of the base member, wherein the three-dimensional effect forming part has a pattern, the pattern having multiple pattern units arranged in a concentric circular, elliptical or polygonal radial form, each of the pattern units having an inclined surface having an inclination angle with respect to the first surface, and wherein when an incident beam is incident to a central portion of the pattern, the pattern guides the incident beam in a first surface direction toward which the first surface looks or a second surface direction toward which a second surface opposite to the first surface looks, thereby displaying a line-shaped beam having a three-dimensional effect in a first path resulting a pattern arrangement direction.

A vehicular illumination module includes a housing, a circuit board accommodated by the housing, an illumination source disposed at the circuit board, and a freeformed lens optic accommodated by the housing. With the illumination source operated to emit light, light emitted by the illumination source passes through the freeformed lens optic and through an outer cover of the housing. The freeformed lens optic is configured such that light emitted by the illumination source that passes through the freeformed lens optic and through the outer cover provides illumination at an illuminated region. The illumination includes background illumination of the illuminated region. Within the illuminated region, a logo is formed by light emitted by the illumination source that passes through the freeformed lens optic. The logo formed by the freeformed lens optic has a light intensity greater than the light intensity of the background illumination of the illuminated region.
