Abstract
This invention relates to a positive photosensitive resin composition that includes a siloxane copolymer of two kinds of reactive silane compounds with specific structures wherein residual impurities such as unreacted monomers and catalysts are minimized, and a UV absorber including one or more kinds of phenol hydroxyl groups capable of crosslinking and an alkoxy group. Accordingly, the resin composition exhibits excellent performances such as sensitivity, resolution, and degree of planarization, and also has excellent weatherability and UV absorbance, thereby providing excellent panel reliability.
