PHOTOSENSITIVE COMPOSITION, PARTITION WALLS, COLOR FILTER AND ORGANIC EL DEVICE

摘要

It is an object of the present invention to provide a photosensitive composition capable of forming partition walls having an upper surface with good ink repellency and open areas which have good ink affinity within which an ink will easily spread. Further, it is an object of the present invention to provide partition walls formed by curing the photosensitive composition, and a color filter and an organic EL device having the partition walls. The photosensitive composition is a photosensitive composition, which comprises a polymer (A) having a side chain containing a group represented by the formula:—CFXRf  (1) or a group represented by the formula: and a side chain containing an ethylenic double bond, a black colorant (B), a photopolymerization initiator (C), and a photosensitive resin (D) containing an acidic group and an ethylenic double bond, wherein the polymer (A) has a number average molecular weight of at least 2×104 and at most 7×104 and a weight average molecular weight of at least 5×104 and at most 25×104.
