PROBLEM TO BE SOLVED: To provide a luminaire capable of evenly illuminating the inside of an annular light guide body, and a display device including the luminaire.SOLUTION: A luminaire includes a light source, and a light guide body having a continuously annular shape. The light source is arranged so that light from the light source is made incident to the inside from a light incident structure provided in the light guide body. The light guide body has such a shape that part of light, made incident from the light incident structure, is totally reflected on the surface of the light guide body to guide light, and the other part of light is extracted from the inner peripheral surface of the annular shape of the light guide body to the outside of the light guide body.SELECTED DRAWING: Figure 3

    【課題】本発明は、環状形状の導光体の内側を均一に照明することのできる照明装置、及びそれを備えた表示装置を提供する。【解決手段】本発明の照明装置は、光源と、連続した環状形状の導光体と、を備え、前記光源は、前記光源からの光が前記導光体に設けられた光入射構造から内部に入射するように配置され、前記導光体は、前記光入射構造から入射した光のうち、一部の光が前記導光体の面で全反射して導光し、他の一部の光が前記導光体の前記環状形状の内周面から前記導光体の外部へ取り出される形状であることを特徴とする。【選択図】図3
