Abstract:
A display for illuminating a liquid crystal display panel with laser light of uniform light quantity distribution, and an illuminator for irradiating with laser light of uniform light quantity distribution. The display includes a liquid crystal display panel (204), laser light sources (205, 206, 207) emitting laser light having wavelengths of green, red, and blue colors, a waveguide plate (201) arranged at the back side of the liquid crystal display panel (204) and performing multiple reflection of laser light, and a diffusion plate (202) arranged at the back side of the waveguide plate (201), diffusing laser light propagating in the waveguide plate (201) and emitting the light toward the liquid crystal display panel (204).
