    • A wavelength selection substrate 23 is configured with a wavelength selection section 23R which transmits only red laser light and reflects other light components, a wavelength selection section 23G which transmits only a green laser light and reflects other light components, and a wavelength selection section 23B which transmits only a blue laser light and reflects other light components. Of laser light 12 outputted from a light guide plate 14, a laser light component that corresponds to a color passing through one of the wavelength selection sections passes through the wavelength selection substrate 23 and enters a liquid crystal panel 22, whereas a laser light component that does not correspond to the color is reflected from the wavelength selection substrate 23 and returns the light guide plate 14. The laser light having returned the light guide plate 14 is reflected from the reflection plate 21 and again enters the wavelength selection substrate 23. This reciprocation of the laser light is repeated until the laser light pass through the wavelength selection section. With this repetition of passing and reflection, the laser light 12 is separated into respective colors of red, green, and blue, and outputted from the wavelength selection substrate 23.
