Definitions
- Photosensitive composition material for forming light shielding film for display using the same, and photosensitive transfer material
- the present invention relates to a photosensitive composition and a material for forming a light shielding film for a display device and a photosensitive transfer material suitable for forming a black matrix and the like of a color filter using the photosensitive composition.
- a black matrix has been required to have a high optical density of 4.0 or more in order to improve the contrast of a display image.
- the thickness of the black matrix is large, the surface smoothness of the color filter using the black matrix is impaired, so the black matrix is required to be formed into a thin film.
- metal thin films have been used in a method of producing a black matrix for a display having high light shielding properties.
- a photoresist is applied on a thin metal film such as chromium formed by vapor deposition or sputtering, and then the photoresist is exposed and developed using a photomask having a pattern for a light shielding film for a display device.
- a step of forming the film by etching the exposed metal thin film and finally removing and removing the photoresist remaining on the metal thin film is included (see, for example, Non-Patent Document 1).
- this method uses a metal thin film, a high light shielding effect can be obtained even if the film thickness is small, but it requires a vacuum film forming process and an etching process such as vapor deposition and sputtering, resulting in high cost.
- the black matrix obtained by this method is a metal film, there is also a problem that the display contrast is low under strong external light whose reflectance is extremely high.
- a method of preparing a black matrix using a low reflection chromium film (such as one having a two-layer strength of metal chromium and chromium oxide) is also proposed. These methods further increase the cost. It is inevitable.
- one of the techniques for obtaining a black matrix having a small environmental load is a method using carbon black (see, for example, Patent Document 1).
- the method comprises the steps of applying a carbon black-containing photosensitive resin composition to a substrate, exposing the dried product to light and developing it into a black matrix.
- the film thickness of the photosensitive resin composition containing carbon black is inevitably increased in order to secure high light-shielding property and optical density. growing.
- the film thickness of the photosensitive resin composition containing carbon black is 1.2 to 1.5 ⁇ m. Therefore, in the photosensitive resin composition containing carbon black, when red, blue, and green pixels are formed after formation of the black matrix, the surface of the color filter is not smooth due to the step of the pixel edge portion, etc. There is a disadvantage that the display quality is degraded.
