Claim 7:
8. The light guide plate according to claim 7, wherein the first stereoscopic image in the space is formed within the predetermined first angle range by the first light source; the second stereoscopic image in the space is formed within the predetermined second angle range by the second light source; and the third stereoscopic image in the space 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 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.
