Abstract
Disclosed is an advertisement display device having a 3D sheet. The advertisement display device having the 3D sheet comprises: a substrate; a backlight unit which is provided on the substrate and irradiates light; and a 3D sheet which is provided on the backlight unit to implement a 3D image by the light irradiated from the backlight unit.
Claims16
An advertisement display device having a three-dimensional (3D) sheet, comprising:
- a substrate;
- a backlight unit disposed on the substrate and emitting light;
- and
- a 3D sheet disposed on the backlight unit to display a 3D image by the light emitted from the backlight unit;
- wherein the 3D sheet comprises:
- a convex lens layer having a pattern of convex lenses formed on a front surface thereof;
- a transparent layer placed under the convex lens layer and having a thickness corresponding to a focal distance of the convex lens;
- and
- an actual image print layer placed under the transparent layer.
