Abstract:
1. A display comprising: a liquid crystal display panel; a laser light source that emits laser light having wavelengths of red, blue and green; a first waveguide plate arranged at a back side of the liquid crystal display panel, the first wave guide plate being capable of performing multiple reflection of the laser light; a diffusion plate arranged at the back side of the first waveguide plate, the diffusion plate being capable of diffusing the laser light propagating in the first waveguide plate to emit the laser light toward the liquid crystal display panel; and a reflection film arranged at a lateral side of the first waveguide plate, the reflection film reflects the laser light, wherein: a plurality of entrances, not covered by the reflection film, is provided in part of the lateral side of the first waveguide plate; the laser light enters the first waveguide plate through at least one of the entrances; a film reflecting light, other than specific light, is formed on each of the entrances; and each laser light, having wavelength of red, blue or green, enters a different one of the entrances through the film.
