Abstract: PROBLEM TO BE SOLVED: To provide a film forming method enabling convenient formation of a photonic-crystalline particulate film having a uniformly oriented state without unevenness and excellent reflection characteristics. SOLUTION: A substrate is immersed in a particulate dispersion dispersed with particulate in a dispersion medium (S1). A liquid film of the particulate dispersion is formed on the surface of the substrate by pulling up the substrate from the particulate dispersion into a gas phase (S2). The dispersing medium is evaporated from the liquid film to dry the substrate so as to form a particulate film composed of particulate assembled in a self-organizing way (S5). After the pulling up of the substrate into the gas phase (S2) and before drying up of the liquid film (S5), the substrate is immersed again in the particulate dispersion (S1), and the immersion of the substrate (S1) and the pulling up of the substrate (S2) are repeated.

Abstract: PROBLEM TO BE SOLVED: To provide a forming method for a particle structure by which a crystal grain boundary and a particle layer having less cracks can be formed, and can increase the mechanical strength by a high crystallinity, and to provide a particle structure having a high crystallinity and a screen which are formed by the forming method. SOLUTION: Cracks which occur when a particle layer is dried can be prevented from occurring by imparting flexibility to an underlayer particle layer by fixing underlayer particles which are accumulated on a base plate by a fixing agent, and a flat surface can be formed on the base plate. Thus, the occurrence of the crystal grain boundary of a particle arrangement layer which is formed on the layer can be prevented from occurring, and the particle structure of a high crystallinity can be formed. Also, the redissolution to a solvent can be prevented from occurring by fixing the underlayer particles or the arrangement particles by a bonding agent, and a uniform surface of the particle layer can be maintained. The particle structure and the screen which are formed by this method have a high crystallinity, and the mechanical strength which can be increased. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a light reflection type optical medium having a reflection layer reflecting specified visible light and possessing structure where the deterioration of image quality caused by scattering external light unrelated to an image by the defect part of the reflection layer is hardly caused, and applied to a reflection type screen or the like.
SOLUTION: The light reflection type optical medium is constituted by laminating a red light reflection layer 2, a green light reflection layer 3 and a blue light reflection layer 4 which are photonic crystal layers on a visible light absorbing layer 1. The reflection layers 2-4 selectively reflect three primary color light beams projected from a projector or the like and form a high-contrast full color image. Visible light absorbing substance is contained in at least one of the reflection layers 2-4 and/or at least one of boundary parts between the layers. Thus, even if the external light is made incident on a screen in a figure, it is partially absorbed by the visible light absorbing substance before it reaches the defect parts of the photonic crystal layers 2-4. Even if the external light is scattered, the scattered light is absorbed by the visible light absorbing substance, so that the scattered light reaching an observer's eye is reduced.
