Claim 8:
9. The light guide plate according to claim 6, wherein the first stereoscopic image is formed in the space within the predetermined first angle range by the first light source; the second stereoscopic image is formed within the predetermined second angle range by the second light source; and the third stereoscopic image is formed within the predetermined third angle range by the third light source such that for set values of x, L, and W, the light guide plate satisfies a system of inequalities expressed by:

90°−arctan(x/2L)≤W 

and

90°−arctan(x/L)≤W, 

where L is an interval between the first light source and the second light source and between the second light source and the third light source, x comprises a distance between the incidence surface and a point in the group of optical-path deflectors, and W is the spread angle of the light from the first light source, the second light source, and the third light source.
