The present invention provides a non-aqueous dispersant capable of forming a resin layer excellent in dispersibility and alkali resistance, and a color filter color filter capable of forming a coating film excellent in heat resistance, high brightness, and alkali resistance. A material dispersion liquid, a color filter having excellent heat resistance, high brightness, and excellent alkali resistance, and a liquid crystal display device and an organic light-emitting display device having the color filter. The non-aqueous dispersant of the present invention is a graft copolymer or a block copolymer; the graft copolymer has a structural unit selected from the following general formula (I) and the following general formula (I ') At least one of the structural units and the structural unit represented by the following general formula (II); the block copolymer has a structural unit selected from the following general formula (I) and the following general formula (I) ') A block portion of at least one of the structural units represented by the following general formula (III) and a block portion comprising a structural unit represented by the following general formula (III). (The symbols in the general formulas (I), (I'), (II) and (III) are as described in the specification). |
