An image projection device is provided to filter a noise generation phenomenon due to a Vf voltage difference of a light emitting material of an LED(Light Emitting Diode) element. An LED driver(16) successively lights on LEDs of an LED light source(17). A light concentrating lens(13) concentrates light emitting from the LED light source on a rest area of a space modulation element. The space modulation element space-modulates light concentrated by the light concentrating lens according to an image signal of a wavelength light corresponding to application timing. A signal processing unit receives an image signal which is inputted from the outside and makes an image signal by the space modulation element. A power supply unit(18) supplies DC power to an LED driver and the signal processor.
