Abstract: Provided is a stereoscopic display device, including: a base substrate transmitting an incident beam; and a three-dimensional effect forming part on a first surface of the base substrate, 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.

Abstract: A lighting device may include a plurality of light sources which are disposed on the circumference of a concentric circle, a light guide which surrounds the light sources and is disposed adjacent to the light sources, and a cover member which surrounds the upper surfaces of the light sources and the upper and side surfaces of the light guide. The light guide has a first surface in the light source direction and a second surface in a direction opposite to the light source which have an inclination with respect to the optical axis of the light emitted from the light sources. The cover member has a light transmitting pattern in a light diffusion region facing the upper surface of the light guide.
