PROBLEM TO BE SOLVED: To provide an illumination device in which an optical member such as an optical sheet is fixed certainly, and wrinkles and bending are hardly generated even if a temperature change in use environment occurs, and which can emit uniform light and has superior quality. SOLUTION: The illumination device 12 is provided with a light source 17 and an optical member 15 arranged on a light outgoing part 15z side of the light source 17. The optical member 15 is pinched by a pair of pinching members and the pinching member is provided with a first pinching member 14 to pinch the optical member 15 from the light source 17 side and second pinching members 16, 16a to pinch the optical member 15 from the opposite side to the light source 17 side. A cushion member 70 is interposed between the optical member 15 and the second pinching members 16, 16a, and the cushion member 70 is equipped with a piezoelectric element 72.
