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 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, wherein the switching section takes the first state in a case in which a voltage is applied to the switching section, and takes the second state in a case in which the voltage fails to be applied to the switching section. |
