    • PROBLEM TO BE SOLVED: To provide an image display apparatus capable of obtaining proper white balance.
      SOLUTION: An inner surface filter 4R and an inner surface filter 4B are placed in between a glass panel 1 and the fluorescent screens of red phosphors 3G and in between the glass panel and the fluorescent screens of blue phosphors 3B, respectively. This gives a red color chromaticity (x, y) of (0.656, 0.343), and a blue color chromaticity of (0.146, 0.063). A brightness ratio among red, green, and blue is given as R:G:B=306:1150:159. When a white color chromaticity (x, y) is determined as being (0.283, 0.298) (=color temperature 9,300 K) and white brightness is determined as being 200 cd/m
      2 , the current density ratio for light emission for each color is given by R:G:B=65:100:98.

    • PURPOSE:To reproduce the environment light in a space wherein the image reproducing device is present faithfully to the environmental light or high presence video effect in a space where a subject is present by reproducing a signal which controls the environmental light in the space where the image reproducing device is present together with a color image signal. CONSTITUTION:The television signal obtained from a camera 100 and the environmental light control signal obtained from an environmental light control signal generator 101 are multiplexed by a signal multiplexing circuit 102 into a television composite signal, which is frequency-converted and transmitted into the space by a transmitter 103. On a reception side, the television composite signal selected by a tuning circuit 106 is separated by a signal separating circuit 107 into the original television signal and environmental light control signal. The television signal obtained by the signal separating circuit 107 is sent to the image reproducing device 108 to display the television image. The obtained environmental light signal, on the other hand, is sent to the control circuit 109 of a lighting device 110, whose voltage value is controlled to control the luminance and chromaticity.

    • PURPOSE:To improve luminance by filling the periphery of a dot or a stripe with metal excellent in heat conductivity and electric conductivity when forming a fluorescent film in dot or stripe shape on a glass substrate to make it into a luminous screen, and then covering the surface of the structure, being made this way, with an aluminum reflection film. CONSTITUTION:On a glass substrate 1 being cleaned enough, a thin aluminum layer 2 by heating deposition in low vacuum and a thick aluminum layer 3 by heating deposition in high vacuum are stacked, and the light absorption factor of the layer 3 is made small beforehand. Next, the space surrounded by this laminate is formed by etching this laminate, and phosphors 4, 5 and 6 are stuffed in these spaces, respectively. Thereafter, the whole face of these phosphors and the laminate where the surfaces are exposed is covered with an aluminum film 7 being a reflective film, and is heat-treated at about 450 deg.C into a fluorescent film. This way, a screen excellent in relative luminous output, luminance maintenance factor, nonelectrification factor, etc., is obtained easily.
