A light emitting device includes a light emitting body disposed on a substrate, which has light emitting sections apart from each other, a light generating member assembled with the light emitting body, and a light reflecting member disposed on the substrate between the light emitting sections. The light generating member receives driving voltages to generate light from the light emitting body, and the light reflecting member reflects light traveling onto the light reflecting member. The light emitting device also includes a light reflection body and a supporting member disposed on the substrate between the light emitting sections. A display device includes the light emitting device, a display panel receiving the light from the light emitting body, which displays images using the light and image data externally provided, and a container receiving the light emitting device and the display panel.
