Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an illumination device with high brightness, especially high in front brightness, high in utilization efficiency of light, easy to respond to large sizing of the device, in which uneven brightness of the front direction is canceled without strict position-matching between a light source and other members, and which is advantageous in productivity and thinning. SOLUTION: Evading utilization or significant reduction of a light diffusion material is realized by a second light beam direction control means, improvement in utilization efficiency of light is achieved, and furthermore, by narrowing down a view angle in Y direction by a first light beam direction control means and concentrating outgoing energy into the front direction, the above problems are solved.
