Abstract: PROBLEM TO BE SOLVED: To provide a stereoscopic image display apparatus capable of forming stereoscopic images of high image quality by properly arranging a plurality of projecting elements and optical paths projected from them. SOLUTION: In the stereoscopic image display apparatus 20, mirrors M3 and M4 are disposed so that the optical path of projection light 12a from each of the projecting elements 3a of a first projecting element group 3 overlap the optical path of projection light 15 from each of the projecting elements 5 of second projecting element group 5. This arrangement makes it possible to minimize a pitch between the optical axes or the image pitch of each of the projecting element groups 3, 5, and 7, which is displayed on a screen 1 or the eyes of an observer 101.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device having a wide color reproduction range. SOLUTION: A light selective transmission filter 32 is provided between a cold-cathode fluorescent lamp 43 as a light source and a liquid crystal panel 2. This light selective transmission filter 32 has wavelength selective transmission characteristics of selectively transmitting light in a prescribed wavelength range in projection light from the cold-cathode fluorescent lamp 43 and guiding it to the liquid crystal panel 2. Consequently, an NTSC ratio is improved by increasing the color purity of illumination light of the liquid crystal panel 2 to expand the color reproduction range. Even when a light selective reflection filter having wavelength selective reflection characteristics of selectively reflecting light in a prescribed wavelength range in the projection light from the cold-cathode fluorescent lamp 43 and guiding it to the liquid crystal panel 2 is provided on a tilt surface of a light guide plate 45, the color reproduction range can be expanded as well.

Abstract: PROBLEM TO BE SOLVED: To realize more uniform, high-contrast display with cholesteric liquid crystal. SOLUTION: In a step S21, bipolar pulses of a voltage V1 are applied to column electrodes Y1 to Y3 T times (a plurality of times) in a specified period and bipolar pulses of a voltage -V2 are applied to row electrodes X1 to X3 T times in the specified time. Consequently, all-planar resetting is carried out. In a step S22, a cholesteric liquid crystal panel is driven by the row electrodes with a selected voltage V3 T times in the specified period by scanning and also selectively applying the column electrodes with bipolar pulses -4V having the opposite characteristics T times in the specified period in timing to the scanning application to the row electrodes, and only liquid crystal at desired pixel positions is changed into a focal conic state to display desired information. This invention is applicable to a liquid crystal display device or liquid crystal driving circuit. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a screen for projection capable of improving all of the contrast, lightness, and field angle of a picture. SOLUTION: Projection light L1 after being reflected by a reflection accelerating layer 2B toward a convergence position P is scattered by a scattering layer 4 arranged selectively at the convergence position P. While the projection light L1 reflected by the reflection accelerating layer 2B is scattered by the scattering layer 4, excessive light such as external light reflected by the reflection accelerating layer 2B is hardly scattered by the scattering layer 4. Using differences between reflecting mechanisms of the projection light L1 and external light makes the reflection range of the projection light L1 much larger than the reflection range of the external light, so the reflecting mechanism and scattering mechanism of the projection light L are both properly controlled. The contrast, lightness, and visual field of a picture are all improved, so a distinctive picture can be appreciated without making the room inner side dark each time a projector system is used.

Abstract: PROBLEM TO BE SOLVED: To present a distinct image without being affected by the brightness of a projection environment.
SOLUTION: A screen for projection on which light from a light source 11 is projected to display an image is provided with an optical thin film 3 made of a dielectric multi-layered film which has a high reflection characteristic to light in a specific wavelength band and has a high transmission characteristic to at least light in a visible wavelength area other than the specific wavelength band, and the film thickness of each layer of the dielectric multi-layered film in the optical thin film 3 is designed by simulation based on a matrix method. In the screen for projection constituted in this manner, the optical thin film 3 functions as what is called a band filter. The optical thin film 3 reflects only light in the specific wavelength band and transmits light having the other wavelengths to function as a wavelength band filter which has a function to separate these light.
