摘要： PROBLEM TO BE SOLVED: To reduce an effect of a light after color separation onto a spectrum distribution due to a very slight dispersion in a spectral transmission factor characteristic of color filters by effectively using the energy of a light from a light source in the picture display device that uses the light separated into four colors or over by the color filters to reproduce a color picture. SOLUTION: In the picture display device that has a light source and 4 kinds of color filters or over, allows the color filters of 4 kinds of over to separate the light emitted from the light source into four colors or over and uses the color-separated light to reproduce a color picture, the spectral transmission factor characteristic of the color filters is selected so that each cut-off wavelength of the color filters of 4 kinds or over is present in a wavelength band that is smaller than a value being a product between an integer and a mean value in a wavelength band from 380 nm to 780 nm of a spectral distribution obtained by multiplying a color matching function with a spectral radiation characteristic of the light emitted from the light source.

摘要： PROBLEM TO BE SOLVED: To obtain a compact and inexpensive projector device projecting a high-luminance picture by collecting and synthesizing only the high-luminance center parts of light beams condensed by a light condensing means from plural light sources, illuminating a finite aperture with the synthesized light and forming a picture. SOLUTION: The light beams emitted from electrode discharge type lamps 1a to 1c to the periphery are respectively condensed by condensing mirrors 3a to 3c. Light intensity patterns 10a to 10c are formed on the lamps 1a to 1c. A collecting means 12 collects and synthesizes only the partial high-intensity light beams 11a to 11c at the center parts of the patterns 10a to 10c, and the synthesized light 13 is inputted in a mixing rod 4. Since the emitted light from the mixing rod 4 is the uniformly distributed high-intensity light obtained by collecting the light beams at the high-intensity parts of the lamps 1a to 1c, an image generating element 6 is more brightly illuminated. Thus, a brighter projected picture on a screen 8 is obtained.
