FIELD: electricity.
SUBSTANCE: illumination device 12 contains a great number of point sources 80 of light, frame 14 comprising point sources 80 of light and an opening 14b through which light passes from point sources 80 and optical element 15 (15a) faced towards point sources 80 of light and capable to cover the opening 14b. Point sources 80 of light are located so that they form LH area with high density of light sources where their layout interval is relatively small and LL area with low density of light sources where their layout interval is relatively big. Light-reflective sections 24 which reflect light emitted by point sources 80 are formed at least in the area brought in coincidence with LL zone with low density of light sources in the optical element 15 (15a).
EFFECT: reducing energy consumption and suppression in generation of light source image.
