摘要： PURPOSE:To easily remove the pigment particles depositing and remaining on the region except on a specified pattern in the development by bringing a sticky material into contact with the glass substrate surface on which a resist film is deposited. CONSTITUTION:A black matrix 1 formed on the glass substrate 2 is not dissolved in the development, contains a resinous component, and sticks firmly to the substrate 2. As a result, the matrix 1 is not released from the substrate 2 even by the attachment and detachment of the sticky material 5. Meanwhile, carbon particles 4 are adhered weakly to the substrate 2, released from the substrate 2 by the attachment and detachment of the material 5, and stuck to the material 5. Accordingly, only the matrix 1 remains on the substrate 2, and a clean glass surface free of carbon particles 4 is exposed at the part where the matrix 1 is not present.

摘要： PURPOSE:To form a flat coating film of a uniform thickness and to obtain a stable color filter having high resolution and free from projections by applying a photosetting resin by transfer with a printing plate and leveling the applied resin by flowing. CONSTITUTION:A light shielding pattern is formed on a transparent base material 4 and a photosetting resin 1 contg. one of red, green and blue pigments in a dispersed state is transferred with a printing plate 3 without sticking to a part on which an image element pattern having other color is formed. The transferred resin 1 is dried, exposed through the base material 4, developed and cured to form an image element pattern. Since the resin 1 is transferred with the printing plate 3, unevenness in thickness due to uneven flowing in the plane direction of the base material 4 is eliminated and a coating film having superior flatness is formed. Since exposure is carried out through the base material 4, only the selectively applied part along the formed light shielding part is exposed and a color filter having high accuracy and free from projections is obtd.

摘要： PURPOSE:To obtain patterns having high definition and good surface smoothness by applying a photopolymn. type photosensitive resin dispersed with a dye material of one color among red, green and blue over the entire surface of a black matrix having prescribed patterns and drying the coating, and further forming oxygen barrier films only to the points where the patterns of picture elements are desired to be formed. CONSTITUTION:The black matrix 4 is provided on the transparent substrate 1 and the photopolymn. type photosensitive resin 6 dispersed with the dye material of one color among red, green and blue is applied on the surface thereof and is dried; further, the oxygen barrier films 8 which stop polymn. and shield oxygen are formed only to the prescribed patterns or places of the surface thereof. The entire surface is then exposed from the non-coated surface. The exposed part below polymn. sensitivity and the parts where there are no oxygen barrier films are developed away. The remaining part is thermally cured to form the patterns of one color. This stage is successively repeated with the other colors as well to form the picture elements 10 of plural colors. The red, green and blue picture elements are provided in this way without using photomasks for forming the respective picture elements. The need for alignment is eliminated and the inexpensive color filters having the high grade image quality and high reliability are obtd.

摘要： PURPOSE:To form defectless and stable patterns by forming 2nd alignment marks in the positions relatively equal to a black matrix on the rear surface of a transparent base material, exposing a sample from the rear surface thereof through a photomask for picture elements aligned by 2nd alignment marks, then developing and curing the same. CONSTITUTION:The sample 6 having the striped or orthogonal grid-shaped black matrix 4 and the alignment marks 5 is formed on the base material 1. The alignment marks 9 are then formed on the rear surface. Further, a photoresist 11 in which a 1st color material is dispersed is coated on the surface of the sample 10 in superposition on the black matrix 4. The photoresist is then irradiated with UV rays via the mask 12 for forming picture elements from the rear surface of the transparent base material 1 and is subjected to a developing stage and curing stage, by which the sample 14 having the 1st picture elements 13 is formed. The mask 12 for forming picture elements and the sample 10 are subjected to mask registration by the alignment marks 9. The good color filter consisting of the picture elements of >=3 colors without having voids and the overlap of the picture elements is obtd. in this way.

摘要： PURPOSE:To simplify the production process by constituting a color filter of red, green and blue picture elements contg. a photosensitive resin composed of a multifunctional acrylate monomer, org. polymer binder and photopolymn. initiator consisting of a trihalomethyl-s-triazine compd. and pigments. CONSTITUTION:This display device has the color filter 10 constituted of polarizing plates 1, 2, glass substrates 3, 4 picture element electrodes 5, oriented films 6, 7, a liquid crystal layer 8, a counter electrode 9, and the red, green and blue picture elements contg. the photosensitive resin and the pigments. The photosensitive resin consists of the basic compsn. consisting of the multifunctional acrylate monomer, the org. polymer binder and the photopolymn. initiator consisting of the trihalomethyl-s-triazine compd. Since the photoresist material prepd. by dispersing the pigments in the photosensitive resin is used, only the patterning after film formation is necessitated and the need for dyeing and fixing stages is eliminated. The number of stages is thereby reduced.
