Abstract
A stereoscopic image display device includes a liquid crystal panel section, a light source section, a light detection section, a light source control section, a shutter glasses section, and a timing generation section generating a light emission drive signal, a light detection gate signal, and shutter switching signals in synchronization with an image synchronization signal. The timing generation section, generates the light emission drive signal which causes each of the regions of the light source section to emit light in accordance with scanning performed in the liquid crystal panel section, and which causes all the regions of the light source section to emit light in a predetermined period, and generates the light detection gate signal which enables detection of the light detection section in the predetermined period, and generates the shutter switching signals for switching left and right shutters to a non-transmissive mode.
