Abstract:
Provided is a photo-sensitive composition capable of yielding pixels having a high translucency and a large refractive index, with a less amount of development residue in the process of formation. The photo-sensitive resin composition contains an ultraviolet absorber represented by Formula (I); a photo-polymerization initiator; and a polymerizable monomer: wherein each of R1, R2 and R3 independently represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms; one of R4 and R5 represents an electron withdrawing group, and the other of R4 and R5 represents —SO2R6, —CO2R6, —COR6, —CN or —CONR6R7; each of R6 and R7 independently represents a hydrogen atom, alkyl group having 1 to 8 carbon atoms or aryl group.
