Abstract
The present invention provides a photosensitive composition which can suppress the generation of a development residue on the surface of an electrode and the corrosion of the electrode to form a black pixel division layer, and also can suppress the generation of off-pixel in an organic EL display device comprising the pixel division layer. Disclosed is a photosensitive composition comprising (a) a pigment, (b) a resin having two or more tertiary amino groups in the molecule, and (c) a photosensitive agent, wherein the component (b) contains a resin having a structure represented by the general formula (1).
Claims14
A negative photosensitive composition comprising:
- (a-1) an organic black pigment or (a-2) a mixed organic black pigment,
- (b) a resin having two or more tertiary amino groups in the molecule, and
- (c) a photosensitive agent, wherein
- the component (b) contains a resin having a structure represented by formula (16):
- wherein, in formula (16),
- * represents a bonding site to a carbon atom,
- A5O, A6O, OA7 and OA8 each independently represent an oxyalkylene group having 1 to 5 carbon atoms,
- A9 and A10 each independently represent an alkylene group having 2 to 6 carbon atoms,
- n1 is an integer and represents 0 to 7,
- X3 to X6 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 5 carbon atoms, and
- a19 to a22 are integers and each independently represent 1 to 100.
