摘要： A light diffusing sheet including a clear film (#1) and two light diffusing layers (#2 and #3) formed consecutively thereon. The diffusing sheet is characterized in that the first light diffusing layer (#2) is a film of clear resin incorporated with a light-diffusing material, and the second light diffusing layer (#3) is a film of clear resin having a corrugated surface structure. The first light diffusing layer (#2) has a thickness of 10 .mu.m to 500 .mu.m and the light diffusing material has a weight concentration of less than 3%. The difference in refractive index between the clear resin and light diffusing material is 0.01 .ltoreq. .DELTA.n .ltoreq. 0.12, and the average particle diameter of the light diffusing material is between 4 .mu.m to 30 .mu.m.

摘要： Provided is a panel light source device through which the light availability is increased. The luminance of light to be outputted by the device in the oblique direction that oversteps the front direction of the device is reduced. The device comprises a light source 2, a reflector 8, a waveguide 3 that receives through its side surfaces the light having been outputted by the light source 2 and reflected by the reflector 8, an output light modulator 6 as provided on the light output surface of the waveguide 3 to modulate the output light from the light output surface of the waveguide 3 toward the front direction of the light output surface, and an input light modulator 9 as provide between the light source 2 and the side surface of the waveguide 3 to modulate the output light from the light source 2 toward the light output surface of the waveguide 3 or toward the back surface of the waveguide 3 opposite to the light output surface thereof.

摘要： An image display apparatus includes an image display device such as, for example, a liquid crystal display panel, having a plurality of dot-shaped picture elements arranged in a two-dimensional pattern, and a diffraction grating disposed on an optical path through which imagewise rays of light emerging from the device travel. To minimize a reduction in quality and contrast of an image displayed by the device, the member has a spatial cut-off frequency chosen to be of a value lying between the sampling frequency, determined by the pitch between picture elements of the image display device, and the Nyquist frequency. For the same purpose, the intensity of .+-.1st order light relative to the intensity of 0-th order light in the diffraction grating is within the range of 60 to 80% at a center wavelength of the image display device, and the sum of the intensity of the 0-th order light and that of the .+-.1st order light relative to that of total diffracted light is equal to or higher than 80% at the center wavelength of the device.
