The alkali developing black photosensitive resin composition for light-shielding partition formation contains (A) photosensitive prepolymer containing a carboxyl group, (B) photoinitiator, (C) black pigment, and (D) light transmitting fine particles as essential components. By using this composition, the light shielding partition 11 of 20 micrometers or more which shows sufficient light shielding property without undercut at the time of image development by the photolithographic method can be formed. In a preferred embodiment, a metal oxide, preferably iron oxide, is used as the (C) black pigment, and inorganic fine particles having a refractive index of 1.40 to 1.90, preferably silica, are used as the (D) microparticles. |
