    Abstract: An optical laminate includes a wavelength selective reflective element, and an absolute phase adjustment layer which is provided on at least one surface side of the wavelength selective reflective element and has optical isotropy, and in which a first region having a first optical path length and a second region having a second optical path length different from the first optical path length are arranged in a pattern with a diffraction grating-like period. The optical laminate reflects light in the specific reflection wavelength region by the wavelength selective reflective element, of light incident from the absolute phase adjustment layer side. In the optical laminate, light which enters the first region of the absolute phase adjustment layer and is reflected by the wavelength selective reflective element and light which enters the second region and is reflected by the wavelength selective reflective element interfere with each other.

    Abstract: A transparent screen includes a substrate capable of transmitting light; and a plurality of dots formed on a surface of the substrate, each of the dots having wavelength-selective reflectivity and being formed of a liquid crystal material having a cholesteric structure, in which the cholesteric structure gives a striped pattern of bright parts and dark parts in a cross-sectional view of the dot observed by a scanning electron microscope, the dot includes a portion having a height that increases continuously to the maximum height in a direction extending from the edge toward the center of the dot, the angle formed by the normal line to a line that is formed by a first one of the dark parts as counted from the surface of the dot on the opposite side of the substrate and the surface of the dot, in the portion, is in the range of 70° to 90°, and a plurality of dot row units in which two or more dots are adjacently arranged along one direction are formed.

    Abstract: The information processor includes an input unit having an illuminating part and an image pickup part, and an input medium having an input surface on which inputting of information is carried out by the input unit which has position coordinates on the input surface coded by a dot pattern. The input unit irradiates light from the illuminating part onto input surface of the input medium. The irradiated light reflects off the dot contained in the dot pattern which is picked up by the image pickup part, and position information of the dot pattern is obtained. The input unit further has an input unit angular position measuring part that measures an angular position of the input unit when the light is irradiated. Based on corrected position information obtained by correction processing based on the angular position, input information, that is specified by the position coordinates is obtained.

    Abstract: An organic EL image display device that includes a light emitting element substrate; and a circularly polarizing plate. The light emitting element substrate includes a reflecting layer and an organic electroluminescent layer group arranged in a matrix form on the reflecting layer. The reflecting layer, the organic electroluminescent layer group, and the circularly polarizing plate are arranged in this order. A polarization separation layer is provided between the organic electroluminescent layer group and the circularly polarizing plate, and includes polarization separation sites arranged in a matrix form corresponding to the organic electroluminescent layer group. The polarization separation site reflects light of one polarization state and transmits light of the other polarization state in light emitted from the corresponding organic electroluminescent layer. The polarization separation site is divided by a visible light transmission region. The organic EL image display device of the present invention has high brightness and little blurring.
