Abstract: PROBLEM TO BE SOLVED: To provide a self-emission type display element capable of maintaining sufficient color reproduction range of wide-view angle.
SOLUTION: The display element is structured by pinching an organic layer having at least a light-emitting layer between a reflecting film and a translucent reflecting film, and making the organic layer work as a resonant part of a resonator structure, for resonating the light emitted from the light-emitting layer. When phase shift, appearing when the light emitted from the light-emitting layer reflects at both ends of the resonant part is Φ (in radian), optical distance of the resonance part, is L, the peak wavelength of a desired spectrum of light in the described light is λ, the display element is structured so that the optical distance L becomes the positive minimum value within the range that satisfies (2L)/λ+Φ/(2π)=m (m means an integer). With this structure, shift quantity of the peak position of a spectrum of light taken from the display element is restricted to less than 30 mm in the range of viewing angle of 0°-60°.

Abstract: PURPOSE:To reduce the occurrence of speckle by impressing an alternating voltage in powder which constitutes a screen and changing the optical path length and the phase of a laser beam transmitted through the screen. CONSTITUTION:The mixed body of the powder 53 having an electrooptical effect with transparent binder 54 is poured into a glass plate 51 so as to mold an electrode 52. The electrodes 52 are alternately connected to terminals 61 and 62 in common and the alternating voltage is supplied to the terminals 61 and 62. Then, a pair of electrodes 52 gives electric field to the powder 53 and the refractive index of the powder 53 is mainly changed according to the alternating voltage. Then, the optical path or the phase of the laser beam LB is finely changed by the change of the refractive index and the occurrence of the speckle is restrained. Thus, the device is prevented from becoming large- scaled, a vibrational noise is not made or faults are not caused many times.

Abstract: PURPOSE:To provide the chemical stability of a reflective metallic layer and the shape stability of the plane or specular surface characteristic thereof and to stabilize optical characteristics by forming the reflective metallic layer of an aluminum alloy contg. titanium. CONSTITUTION:The reflective metallic layer 3 of the information recording medium having the reflective metallic layer 3 is formed of the Al alloy layer contg. at least 0.1-10wt%, more particularly 0.2-3wt% Ti in particular. Said layer is constituted by a vapor phase film forming method such as, for example, vacuum deposition or sputtering. The information recording medium with the reflective metallic layer 3 consisting of the Al alloy contg. Ti has the stable and excellent characteristics. The reason thereof lies in that the reflective metallic layer 3 consisting of the Al alloy contg. Ti is highly resistant to corrosion and hardly grows crystals. The effect of providing the corrosion resistance and averting the crystal growth is low if the content of Ti in the reflective metallic layer 3 is
