Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0027] First, referring to FIG. 1, the structure of a liquid crystal display device as an image display device according to an embodiment of the present invention will be described below. In this embodiment, "front" means the side close to the light source seen from the object; and "rear" means the side opposite to the light source seen from the object.

[0028] FIG. 1 shows a schematic view of a liquid crystal display device according to an embodiment when viewed directly from above or from the side. The liquid crystal display device is a three-panel system projection type color liquid crystal display device, which includes a first optical system 1 and a second optical system 2 .

[0029] The first optical system 1 includes a first light source 11 , a second light source 21 and a PS separation / synthesis unit 16 . The central axis 10 (he...

Abstract

Provided are an illumination optical system having superior color rendering properties while ensuring sufficient illuminance, an image display apparatus comprising the illumination optical system and a spatial modulation device illuminated by the illumination optical system, and a method of illuminating the spatial modulation device. A first light source (11), a second light source (21) having a different emission spectrum from an emission spectrum of the first light source (11), and a replacement optical system replacing light in a specific waveband in a luminous flux (L1) from the first light source (11) with a luminous flux (L2) from the second light source (21) are comprised, and the light in the specific waveband with weak light intensity in the luminous flux (L1) from the first light source (11) is replaced with the luminous flux (L2) with sufficient intensity from the second light source (21). Thereby, a white balance can be kept without reducing the illuminance more than necessary, and superior color rendering properties can be exhibited.

Description

technical field [0001] The present invention relates to an illumination optical system for illuminating an object in a balanced manner, an image display device including the illumination optical system, a space conditioner illuminated by the illumination optical system, and a method for illuminating the space conditioner. Background technique [0002] In recent years, for example, a projection type liquid crystal display device has been widely used, which uses a space regulator typified by a liquid crystal panel as an optical switching device, and uses a projection optical system such as a liquid crystal projector to project the The image is enlarged and projected on the screen. In this type of liquid crystal display device, a single-panel system composed of one liquid crystal panel including three color filters of B (blue), R (red), and G (green), and a (blue), R (red), G (green) optical paths of three monochrome liquid crystal panels constitute a three-panel system.
