Patent ID: 8574794

Claim:
A photosensitive resin composition, comprising: an alkali-soluble acrylic binder resin; and a cardo-based binder resin, wherein the cardo-based binder resin includes a fluorine functional group; wherein when a cured resin film is formed using the composition, the cured resin film has an optical density (OD) of 2.0 or more per unit thickness (2.0 μm), a contact angle of 85°-110° to water, and a contact angle of 35°-50° to 2-ethoxyethanol; and wherein the alkali-soluble acrylic binder resin is a polymer of a composition including a monomer represented by C(O)OCHCH 2 (CF 2 ) x CF 3 (here, x is an integer of 1-12), and includes 5-50 wt % of fluorine.
