Abstract: Disclosed are light emitting modules and automobile illumination devices including the same. The light emitting module comprises a module substrate, a light emitting device on the module substrate, and a light guide structure apart from the module substrate and in plan view surrounding the light emitting device. The light emitting device comprises a first pixel and a second pixel each including a light emitting diode (LED) chip that emits light whose wavelength falls within a range of blue color or ultraviolet ray, and a wavelength conversion material on a top surface of at least one of the first and second pixels.
