Abstract
The present invention relates to a method for manufacturing a light emitting knob based on a novel process that is capable of preventing a letter that is separated from a light blocking metal plate at a display window forming step and a surface treatment step from being separated from a resin layer irrespective of the shape or the type of the letter, which constitutes a light emitting display window, thereby considerably reducing a defect rate. The method includes a metal plate processing step, a display groove forming step, a resin layer coupling step, and a display window forming step.
