Abstract
An optical device, a method of manufacturing same, and a vehicle therefor are provided. The optical device includes a printed circuit board (PCB); light emitting diodes (LEDs) spaced apart from each other on the PCB, a light guide layer with the LEDs embedded therein, and a pattern layer stacked on a side surface of the light guide layer to implement a three-dimensional luminescent image using light from the LEDs. The LEDs include at least top-emitting LEDs and/or side-emitting LEDs.
