[Problem] The purpose of the present invention is to provide a positive photosensitive resin composition capable of forming a cured film which is used for liquid-crystal display elements, organic EL display elements, and the like and has a surface with high water repellency and high oil repellency, which has little residue after patterning, and on which an organic functional ink does not overflow but wet-spreads satisfactorily within the pattern formed by patterning. [Solution] This positive photosensitive resin composition contains component (A), component (B), component (C), component (D), component (E), and solvent (F) below and contains no photoacid generator, the positive photosensitive resin composition being capable of forming a cured film. Component (A): at least one alkali-soluble polymer obtained by polymerizing a monomer mixture including (A-I) below; (A-I): N-substituted maleimide compound; component (B): surfactant; component (C): compound having a vinyl ether group; component (D): photosensitizer; component (E): crosslinking agent; and (F) solvent.

One or more punch pattern methods are applied (402) to generate a spatial distribution of punches that forms a semi-random pattern for an image display screen. The image display screen is punched (404) with the spatial distribution of punches that forms the semi-random pattern. An image rendering light is emitted (406) by a light projector toward the image display screen mounted in an image rendering environment. The image display screen reflects (408) at least a portion of the image rendering light emitted from the light projector toward a viewer.

Precision screen printing is described that can enable sub-micron uniformity of metallized material printed on green sheet ceramic. In some examples, a disc having electrical traces is formed by screen printing a paste containing metal in a pattern of electrical traces on a ceramic green sheet, and processing the printed green sheet to form a disc of a workpiece carrier. In some examples, the printing includes applying a squeegee of a screen printing machine to the printed green sheet in a squeegee direction while the green sheet is on a printer bed of the screen printing machine. The method further includes mapping the printer bed at a plurality of locations along the squeegee direction, identifying non-uniformities in the printer bed mapping, and modifying a printer controller of the screen printing machine to compensate for the mapped non-uniformities in the printer bed.

One or more perforation hole pattern methods are applied (402) to generate a spatial distribution of perforation holes forming a semi-random pattern for an image display screen. The image display screen is perforated (404) with the spatial distribution of perforation holes forming the semi-random pattern. Image rendering light is emitted (406) with a light projector toward the image display screen that is installed in an image rendering environment. At least a portion of the image rendering light emitted from the light projector is reflected (408) by the image display screen, toward a viewer.

The present invention provides a positive photosensitive resin composition, which can be used for liquid crystal display elements, organic EL display elements, etc., and has a cured film surface with high hydrophobicity and high oleophobicity, less residue after pattern formation, and a cured film that does not overflow in the pattern after pattern formation and is well wetted and spread. The present invention is a positive photosensitive resin composition that can form a cured film, which contains the following (A) component, (B) component, (C) component, (D) component, (E) component and (F) solvent, but does not contain a photoacid generator, (A) component: at least one alkali-soluble polymer obtained by polymerizing a monomer mixture containing the following (A-I), (A-I): N-substituted maleimide compound, (B) component: surfactant, (C) component: compound having a vinyl ether group, (D) component: photosensitizer, (E) component: crosslinking agent, (F) solvent.

(D) a colorant including a blue pigment; (E) a solvent; (F) a thiol-based compound; and (G) a silane coupling agent; wherein the thiol-based compound and the silane coupling agent are each independently contained in an amount of 0.1% by weight or more and less than 0.3% by weight based on the total amount of the photosensitive resin composition; a photosensitive resin film produced using the photosensitive resin composition; a color filter including the photosensitive resin film; and a display device including the color filter.
