    Abstract: PROBLEM TO BE SOLVED: To seal a display material and electrodes without a non-display part being present at the boundary between adjacent planar display elements when a plurality of planar display elements are arranged to constitute a screen. SOLUTION: A display material and an electrode 3 intervene between a first transparent substrate 2 located on a display surface and a second substrate 4 made from the same material as the transparent substrate 2 and located on the back face, and thin plates 8 made from the same material as the substrate 2 are bonded to the side faces of the substrates 2, 4 with a transparent adhesive 7 having a reflectivity about equal to that of the substrate 2. The distance (x) from a pixel PX located at the farthest end of the substrate face of each of the substrates 2, 4 to the surface of each thin plate 8 is about half the gap (g) between pixels PX.

    Abstract: PROBLEM TO BE SOLVED: To provide a laser device capable of preventing laser oscillation from a removed laser resonator when the laser resonator is removed from a laser device for the purpose of exchange. SOLUTION: This laser device is provided with laser resonators 1, 2, 3, and 4 for emitting laser beams under prescribed laser oscillation conditions and case bodies 6 and 7 including the laser resonators. This laser device is fixed to the case bodies so that the laser oscillation condition cannot be irreversibly fulfilled when the laser resonators are removed from the case bodies.

    Abstract: PROBLEM TO BE SOLVED: To obtain the projection type display device which can form a display image of high resolution with high color purity without using any color filter by setting the half-value wavelength of transmission characteristics of a plane of polarization crossing a specific plane of polarization at right angles to the short-wavelength or long-wavelength side of peak wavelength. SOLUTION: Illumination S-polarized light is supplied to respective liquid- crystal display panels 29R, 29G, and 29B and then the P-polarized component of video light which is made incident as the composite light of the S-polarized light and P-polarized light corresponding to respective color signals is projected on a screen 37, thereby forming a display image. When the display image based upon desired spectral characteristics is displayed, a color separating mirror 36 has its characteristics selected so that the half-wave wavelength of the transmissivity to the P-polarized light and the half-value wavelength of the transmissivity to the S-polarized light are positioned on the long-wavelength side and short-wavelength side of the peak wavelength of the spectral characteristics of a light source 2. Consequently, the color separating mirror 36 prevents the resolution and color purity from being deteriorated.
