Process for producing substrate having partition walls and pixels formed thereon

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 the following photosensitive composition, 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 above 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:
• photosensitive composition:
• a photosensitive composition comprising a polymer (A) having a side chain containing a group represented by the following formula 1 or a group represented by the following formula 2 and a side chain containing an ethylenic double bond in one molecule:
• —CFXRf (1)
• wherein X is a hydrogen atom, a fluorine atom or a trifluoromethyl group, and Rf is an alkyl group having at most 20 carbon atoms which may have an etheric oxygen atom, at least one of hydrogen atoms of which is substituted by a fluorine atom, or a fluorine atom;
• —(SiR1R2O)n—SiR1R2R3 (2)
• wherein each of R1 and R2 which are independent of each other, is a hydrogen atom, an alkyl group, a cycloalkyl group or an aryl group, R3 is a hydrogen atom or a C1-10 organic group, and n is an integer of from 1 to 200.
