Abstract
An illumination control device for illuminating an light modulation information display device with light includes: at least one illumination device for irradiating light which is generated through discharging; and a driving waveform generation section for controlling the light which is irradiated from the at least one illumination device to the light modulation information display device. The light modulation information display device is operable so as to have a first period and a second period during which an image is displayed. During the first period, the driving waveform generation section applies a first voltage to the at least one illumination device, the first voltage causing the at least one illumination device to be turned entirely-ON. During the second period, the driving waveform generation section applies a second voltage to at least a portion of the at least one illumination device.
