PURPOSE: A light emitting control knob is provided to improve the visibility of a light emitting display window by forming a light diffusion resin layer on the upper side of a knob body exposed by the light emitting display window. CONSTITUTION: A knob body(10) is made of transparent or translucent plastic materials to transmit light. A light blocking metal plate(20) is adhered to the upper side of the knob body with an adhesive. The light blocking metal plate forms a light blocking surface in the remaining part except a light emitting display window(21). The light emitting display window is formed with characters or symbols which show a function controlled by a light emitting control knob. A light diffusion resin layer(40) is laminated on the upper side of the knob body exposed through the light emitting display window. |
