Illuminating device and display device
First Claim
1. A illuminating device used for illumination of a reflective type liquid crystal display device, comprising:
- a light source part that is arranged in a lateral position in relation to the image display surface of the reflective type liquid crystal display device, that emits linear polarized light in a direction substantially parallel to the image display surface; and
a plurality of reflecting members, arranged in front of the image display surface of the reflective type liquid crystal display device and separated from the image display surface, that reflect the light emitted from the light source part and inject that light substantially vertically in relation to the image display surface,wherein the plurality of reflective members are arranged to the front of part of the region of the image display surface of the reflective type liquid crystal display device and at least part of the light injected into the image display surface that is reflected by the image display surface is emitted toward the forward side of the image display surface.

Abstract
To provide a illuminating device that is of small size, light weight and that has lower production costs for illuminating a reflective type liquid crystal display device that performs high contrast, moreover high definition and high-quality image display, thereby enabling realization of an image display that is of small size and light weight and that can be produced at low-cost. The display device comprises a light source 5 disposed in a lateral position in relation to the image display surface 3 of the reflective type liquid crystal display device 2, that emits linearly polarized light, and a plurality of reflecting members 6 disposed to the front of the image display surface 3 and separated from the image display surface 3, that reflect light emitted from the light source 5 and inject this light substantially perpendicularly in relation to the image display surface 3. The plurality of reflecting members 6 are arranged to the front of part of the region of the image display surface 3 of the reflective type liquid crystal display device 2 and at least part of the light injected into the image display surface 3 that is reflected by the image display surface 3 is emitted toward the forward side of the image display surface 3.

10. A illuminating device that utilizes illumination of a reflective type liquid crystal display device, comprising:
-
a light source arranged in a lateral position in relation to the image display surface of a reflective type liquid crystal display device, that emits light that is substantially parallel to the image display surface; and bologram elements disposed in front of the image display surface of the reflective type liquid crystal display device and separated from the image display surface, that diffracts at least a part of the light emitted from the light source, and injects this diffracted light into the image display surface at an angle within a determined range centered around a direction perpendicular to the image display surface, wherein light is injected into the image display surface of the reflective type liquid crystal display device and modulated light modulated and reflected by this reflective type liquid crystal display device passes the hologram elements and is emitted to the frontal side of the image display surface. - View Dependent Claims (11, 12, 13)
