METHOD FOR PRODUCING SUBSTRATE WITH PARTITION WALL AND PIXEL FORMED THEREON

摘要

To provide a process for producing a substrate having partition walls and pixels formed thereon, by which it is possible to obtain partition walls excellent in the liquid repellency and pixels having an ink layer excellent in the uniformity in the thickness. A process for producing a substrate having partition walls and pixels formed thereon, which comprises forming partition walls on a substrate by a step (11) of coating the substrate with a photosensitive composition comprising a polymer (A) having a side chain containing a fluorine atom-containing group or a silicon atom-containing group and a side chain containing an ethylenic double bond in one molecule, a step (12) of drying a coating film of the photosensitive composition, an exposure step (13), a development step (14) and a post-exposure step (15); and forming a film by a step (21) of injecting an ink within dots which are regions partitioned by the partition walls and a step (22) of drying a coating film of the ink, the film satisfying (h1-h2)/h1<0.3 where h1 is the maximum thickness of an ink layer in one dot and h2 is the minimum thickness, thereby to obtain pixels.
