Silane-based compounds and photosensitive resin composition comprising the same

Disclosed is a photosensitive resin composition suitable for use in a transflective liquid crystal display (LCD). The photosensitive resin composition uses, as an alkali-soluble binder resin, a blend of two kinds of binder resins. The first binder resin has a weight average molecular weight greater than or equal to 1,000 but lower than 20,000 and contains no reactive group. The second binder resin has a weight average molecular weight greater than or equal to 20,000 but lower than 80,000 and contains reactive groups. The photosensitive resin composition has good adhesion to an underlying substrate while forming a high resolution fine pattern.

Photosensitive resin composition

The present invention relates to a photoactive compound of a novel structure represented by Chemical Formula 1 below In Chemical Formula 1, Rand R, R, and A are as defined in the specification, and a photosensitive resin composition comprising the same. The photoactive compound of the present invention comprises a nitro group and a phosphonate structure and thus exhibits excellent sensitivity through efficient absorption for UV light, excellent compatibility between the photoactive compound and the alkali-soluble binder resin, and an improved solubility of the photosensitive resin composition.
