PROBLEM TO BE SOLVED: To appropriately reduce color unevenness with a small loss of an amount of light, without enlarging an illumination optical system.SOLUTION: A light source section 10 has an LED chip that emits a light fux of several colors. A converging optical system 12 respectively converges the emerging light flux from each LED chip of the light source section 10. A reflection member 11 has a side wall section along a boundary between adjacent two LED chips of the light source section 10 disposed toward the converging optical system 12, and each side wall section has a reflection surface. |
