IMAGE DISPLAY DEVICE AND HEAD-MOUNTED DISPLAY

摘要

An image display device includes a signal light generation section including a light source section adapted to emit a light beam, a light scanner adapted to perform a scan with the light beam emitted by the light source section, and a switching section disposed between the light source section and the light scanner, and being adapted to switch between a first state of making the light beam emitted by the light source section enter the light scanner, and a second state of preventing the light beam emitted by the light source section from entering the light scanner. The switching section switches to first state when a voltage is applied to the switching section and switches to the second state when the voltage fails to be applied to the switching section.
