Abstract: A coating film is formed on the surface of a member during a coating process wherein a coating head and the member are moved relatively. Mixing plural kinds of coating liquid and supplying the resultant mixed liquid to the coating head are carried out substantially simultaneously. The method is used, for example, in producing a color filter of a liquid crystal display device.

Abstract: A disclosure is directed to a coating method of a liquid on the surface of a member during a coating head and the member are moved relatively, thereby forming a coating film. An improvement resides in that a process of mixing plural kinds of coating liquid with one another, and a process of supplying the resultant mixed liquid to the coating head are substantially, simultaneously carried out. The method is used, for example, in producing a color filter of a liquid crystal display device.

Abstract: A coating apparatus comprising a plurality of paint supply devices, a mouthpiece for dispensing a paint supplied from the paint supply devices, and a stage for holding a coated object. The mouthpiece comprises a plurality of outlet ports. Also, a coating method comprising relatively moving a mouthpiece and a coated object to coat the coated object with paint in which a diluent is added to the paint to form a paint/diluent mixture upon the start of the coating process. This paint/diluent mixture is used to coat the coated object upon the start of the coating process and until the process reaches a steady state. The flow of diluent is then stopped and the coating process is continued using only the paint in a steady state coating process. The flow of diluent is then started again to form a paint/diluent mixture as the coating process ends. A coating with a highly uniform thickness along the entire length of the coated object is produced by this method.

Optical film thickness (nd) of the aluminum oxide film is within a range of:.lambda./11.1 to .lambda./5.0;.lambda./4.11 to .lambda./2.89;.lambda./1.73 to .lambda./1.47; or.lambda./1.28 to .lambda./1.20wherein reflectance of the incident light is substantially constant when the angle of incidence on the reflection face(s) is between 10.degree. and 55.degree..

Abstract: Disclosed are a method and an apparatus for forming a specular protective film in which the intensity of reflected light is made even with a variation in the angle of incidence of the incident light. In the anodic oxidation treatment, the current value applied to a plurality of specular parts is sampled at a predetermined interval (S301), and each sampled value is integrated over time (S302) and the average value is obtained. A comparison is made between an obtained average value and a preset value, and if the average value is greater, the application of current to all the specular parts is stopped (S303). The preset value is the amount of electricity conducted to form an anodic oxide film having a film thickness corresponding to a desired reflectance which is determined from the relation between the preset film thickness of anodic oxide film and the reflectance.

Abstract: An optical device is composed of: a transparent base plate formed of a glass or a macromolecular resin; a first layer formed of a substance having a refractive index of 1.58 or higher; and a second layer formed of an amorphous transparent fluorocarbon resin having a refractive index of 1.35 or lower. The second layer is farther from the transparent base plate than the first layer from the transparent base plate. The first and second layer constitute a film for preventing reflection. Optionally, adhesive layers are provided between the transparent base plate and the first layer and between the first layer and the second layer. Further optionally, the surfaces of the transparent base plate and the first layer are treated in order to enhance adhesion between the contact surfaces.
