20100007818 | ILLUMINATION APPARATUS, ILLUMINATING METHOD AND DISPLAY APPARATUS - A light source is arranged at a side face of a light guide plate, and a beam direction regulator and a reflection plate are sequentially arranged at a side of the light guide plate opposite to an illumination direction. Furthermore, a transmittance/scattering switching device is arranged at an illumination direction side of the light guide plate. Light from the light source entering the light guide plate emerges in a direction opposite to the illumination direction, passes through the beam direction regulator, and is reflected by the reflection plate. The reflected light once again passes through the beam direction regulator, passes through the light guide plate, enters the transmittance/scattering switching device, and then emerges as light in a transmitting state or a scattering state. Thus, the occurrence of moiré effects and uneven luminance are suppressed, and an illumination apparatus capable of controlling an emerging light angular distribution is obtained. | 01-14-2010 |
