摘要： Provided is a high decorative illumination device that utilizes a lenticular lens sheet. An illumination device (10) includes a lenticular lens sheet (11) and an LED light source (12). The lenticular lens sheet (11) is curved in an X direction, and a convex surface (11A) is formed in a concave shape. The LED light source (12) is positioned inside the convex surface (11 A) of the lenticular lens sheet (11). First and second reflection components (R1 and R2) from first and second bright points (S1 and S2) which are acquired by reflecting irradiation light rays from the LED light source (12) from plano-convex cylindrical lenses (14) are incident on left and right eyes (LE and RE) of an observer who observes the illumination device (10). The observer observes a virtual image (K1) as if a light emitter is present in a position in which the first and second reflection components (R1 and R2) cross each other.

The illumination optical system includes: a light source (20) configured to apply light onto an end surface of one of a first substrate and a second substrate; and a light modulation layer (30) provided in a gap between the first substrate and the second substrate. The illumination optical system includes an electrode configured to generate an electric filed that generates, in the light modulation layer (30), a plurality of linear scattering regions (30B) in a three-dimensional mode, and to generate an electric field that generates, in the light modulation layer, a planar scattering region in a two-dimensional display mode. The lenses are arranged side by side in a direction in which the linear scattering regions extend, and are also arranged side by side in a direction intersecting with the direction in which the linear scattering regions extend.
