Abstract: PURPOSE:To obtain such a forming method that thickness of a protective film is gradually and smoothly decreased in the peripheral part to the peripheral part of a transparent substrate, by using different two or more kinds of developers or etching liquids and developing or etching in two or more steps. CONSTITUTION:Development or etching is done in two or more steps by using different two or more kinds of developers or etching liquids. Namely, two- or more-step treatment ('treatment' means development or etching) is performed in the developing process when the transparent protective film has photosensitive performance or in the etching process when the film has no photosensitivity. These two or more kinds of treating liquids mean liquids having different liquid compsns. (solute, concn.) and temp. from each other. Treatment is preferably performed in two or more steps. By performing the treatment in two or more steps, the transparent protective film after treated can be formed to have the peripheral part having thickness gradually and smoothly decreased to the peripheral part of a transparent substrate.

Abstract: PROBLEM TO BE SOLVED: To prevent faulty display such as an afterimage, etc., from occurring by setting the tilt angle of the surface of a color filter on the pattern edge part of a black matrix to be smaller than a specified value. SOLUTION: This color filter is provided with the black matrix 24 and a coloring layer 26 formed on the aperture part of the black matrix 24 and a part of the black matrix 24 on a transparent base plate 22. The layer 26 is flat in the vicinity of the center of the aperture part of the black matrix 24 but swells on the pattern edge part of the black matrix 24 because of the black matrix 24. It is conceivable to form a transparent protective film 28 and a transference electrode 30 on the layer 26 as necessary but the swell on the black matrix 24 is not eliminated. By grinding the surface of the layer 26, the tilt angle θ of the layer 26 on the pattern edge part of the black matrix 24 is set to =1.6 μm.

Abstract: PURPOSE: To improve uniformity of film thickness, spectral characteristics, flatness, processing accuracy, etc., by sensing a relative position of a stage with respect to a coating material delivery device to control a delivery state of coating material from a coating material feed device. CONSTITUTION: After a predetermined quantity of coating material is drawn from a coating material tank 1 to a microcylinder pump 2, a switch valve 2a is changed over to a mouth piece 3a and a stage 4 is driven normally and a material 8 to be coated is moved to just under the piece 3a and stopped. Next, the piece 3a is lowered to ensure a predetermined clearance. Simultaneously with the lowering action, the microcylinder pump 2 is actuated to deliver coating material. And the stage 4 is stopped for a predetermined time period to form a coating material bead over the entire region in a predetermined transfer direction between the piece 3a and the material 8. And the stage 4 is caused to run normally to effect coating operation. When the stage 4 has been moved to a coating terminal position, a position sensor 5 senses it to switch the valve 2a to a coating material suction side to prepare a following coating operation.

Abstract: PURPOSE: To make it possible to set a high suction packing operation speed and to assure the uniformity of a coating film by providing coating material suction routes from a coating material tank to a piston type fixed delivery pump with positive pressure holding means of the coating material. CONSTITUTION: The coating material is sucked by the piston type fixed delivery pump 2 from a coating material tank 1 through a first liquid feed pipeline 1a and a selector valve 2a. The coating material is supplied through a selector valve 2b and a second liquid feed pipeline 3b to a slit 3a for discharging the coating material of a coating material discharging device 3. A material 8 to be coated is attracted and held by a stage 4 and is coated by nearly intersecting the lower prescribed position of the coating material discharging device 3 with the coating material discharge direction. At this time, the routes 1a, 2a from the coating material tank 1 to the piston type fixed delivery pump 2 are provided with the holding means (pressure regulating valves, release valves, etc.) for holding the coating material at a positive pressure. The generation of cavitation and air bubbles is then prevented and the high uniformity of the coating material supply is attained.

Abstract: PURPOSE: To keep uniformity of a film thickness near a coating start place of a sample to be coated continuously and to suppress a stripe-like defect generating at the coating start place to a coating direction by discharging a paint before the start of coating and/or after the finish of coating, then wiping a lip part of a mouth piece. CONSTITUTION: In a producing method of a coated film 6 on a substrate 5 by applying a paint by using a slit die coater mouth piece provided with a slit 3 for discharging a paint, the paint is discharged before wiping the mouth piece lip part, that is, before the start of coating or after the finish of coating. An air space is generated in the slit 3 when the paint is suck from the mouth piece slit 3 at the coating finished position of the substrate 5 by subjecting a pump 8 for paint supplying to inverted driving in order to keep a coated film 6 thickness from increasing near coating finished place, but the air space is filled with the paint and arranged at a lip tip surface by discharging the paint before wiping the tip part. That is, the coating is started reproduciblely in a state in which the slit 3 is filled with the paint.
