    摘要: A laser light source (1) emits a beam. A collimator lens (2) converts the beam emitted from the laser light source (1) into first substantially parallel light. A lenticular lens (3) expands a beam of the first substantially parallel light converted by the collimator lens (2) into a linear shape in a first direction. A Fresnel lens (4) converts the beam expanded in the first direction by the lenticular lens (3) into second substantially parallel light. A free curved surface mirror (5) has a reflecting surface formed into a free curved surface, and expands a beam of the second substantially parallel light converted by the Fresnel lens (4) into a planar shape in a second direction orthogonal to the first direction. This arrangement enables to provide a planar illumination device with a small thickness and high light use efficiency.

    摘要: A surface illumination apparatus is provided which includes a laser light source and a light guide plate upon which a laser beam emitted from the laser light source is incident through an end-surface portion and from which the laser beam is emitted through a main-surface portion on one side thereof. The laser beam is incident through an end-surface portion at an inclination angle to a main-surface portion on the other side which faces the one main-surface portion of the light guide plate, undergoes a change in the optical-path direction thereof by the other main-surface portion, is incident on the one main-surface portion and is emitted as a substantially parallel beam from the one main-surface portion.

    摘要: 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.
