  • Photosensitive resin composition
    Patent number: 8173729
    Abstract: The present invention relates to a photosensitive resin composition, particularly to a photosensitive resin composition for forming an interlayer organic insulating film for TFT-LCD, comprising 0.01 to 20 wt % of UV stabilizer or radical scavenger. The photosensitive resin composition of the present invention can be used for forming an interlayer organic insulating film for TFT-LCD to improve active unfilled area upon over exposure in liquid crystal photo-alignment process, can easily control resolution of pattern, and is particularly suitable for forming a planarization layer of an interlayer organic insulating film.
