摘要： A liquid crystal display device includes a reflective color filter arranged to intersect with an optical path of light emerging from a principal surface of a light guide plate, and a recycle portion arranged at a side of the light guide plate opposite to the reflective color filter. Out of light incident on the light guide plate, light reflected by the reflective color filter is returned to the reflected color filter again by being reflected by the recycle portion via the light guide plate.

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.

摘要： An LCD backlight has a light source that emits a laser light, a lens, a mirror, a rotary polygon mirror, a scanning lens and a return mirror constituting a transforming optical system that transforms the laser light from the light source to a linear light. A light guiding plate allows the linear light to enter and emits two-dimensional light in the horizontal direction. An emission end face of the light source is disposed in a rear face side of the light guiding plate so that a surface normal line thereof is in the horizontal direction or is inclined downward from the horizontal direction. The lens, mirror and scanning lens are disposed in the rear face side of the light guiding plate, so that surface normal lines of the light transmission surface and light reflection surface thereof are all in the horizontal direction or are inclined downward from the horizontal direction.

摘要： An optical scanning device capable of stably and uniformly performing linear optical scanning by using a high-brightness light source is provided. The device includes: at least one laser light source (11) for emitting a laser light; a deflection section (15) for deflecting and scanning the laser light emitted from the at least one laser light source (11); and a light guide plate (17) of which a side surface is irradiated with the laser light deflected and scanned by the deflection section (15). The at least one laser light source (11) includes a multi-mode fiber light source, or a broad-stripe semiconductor laser light source arranged such that a vertical direction of a stripe structure is parallel to a scanning direction. An exit pupil in a thickness direction, which is perpendicular to the scanning direction, is formed at least in one area on the side surface of the light guide plate (17).
