Problems solved by technology

However, when these conventional photosensitive resins are used in the manufacture of optical filters, they are coated on inorganic films such as transparent conductive films (such as indium tin oxide ITO evaporated films, IZO, etc.) or silicon nitride and silicon oxide films. , it has the disadvantage of poor edge smoothness, which will cause cracks or faults on the pixel layer

Abstract

The invention relates to a blue photosensitive resin composition, and the smoothness of the edge profile formed thereby after development is good. Furthermore, the contrast of a liquid crystal display device manufactured with the blue photosensitive resin composition is excellent. The invention also provides a method for manufacturing a color filter, a color filter and a liquid crystal display device are also provided in the invention.

Description

technical field [0001] The invention relates to a blue photosensitive resin composition for a color filter of a liquid crystal display. In particular, it relates to a blue photosensitive resin composition for a color filter with good edge smoothness of a pattern formed after development and good contrast of the obtained liquid crystal display device. Background technique [0002] In the color filter manufacturing process, the use of photosensitive resin is an important step. The existing method of manufacturing color filters is to form a photosensitive resin composition on a transparent substrate, dry the composition through prebake, and further perform steps such as exposure, development, and postbake to obtain Pixels of various colors and light-shielding layers. For example, Japanese Patent Publication Nos. Hei 2-144502 and Hei 3-53201 disclose methods for manufacturing pixels of various colors, and Japanese Patent Laid-Open No. Hei 6-35188 discloses a method for manufac...
