To make it possible to improve display quality of a display device.SOLUTION: There is provided a liquid crystal material composition which comprises a liquid crystal mixture containing at least each one of first, second and third liquid crystal compounds, a polymerization initiator and a monomer having acryloyl groups at both terminals. The first liquid crystal compound has a first aromatic ring having a halogen group and a halogen group, has a second aromatic ring bonded to the first aromatic ring through a first bond and contains a third aromatic ring bonded to the second aromatic ring through a second bond. The second liquid crystal compound has the first aromatic ring, the second aromatic ring and an aliphatic group and contains a first alicyclic group bonded to the second aromatic ring through a third bond. The third liquid crystal compound has a fourth aromatic ring, a fifth aromatic ring bonded to the fourth aromatic ring through a fourth bond and an alicyclic group, has a second alicyclic group bonded to the fourth aromatic ring through a fifth bond and an aliphatic group and contains a third alicyclic group bonded to the fifth aromatic ring through a sixth bond.SELECTED DRAWING: None 【課題】表示装置の表示品位の向上を可能にする。【解決手段】第１、２及び３液晶化合物を少なくとも１種ずつ含む液晶混合物、重合開始剤、並びに両末端にアクリロイル基を有するモノマーを含む液晶材料組成物。第１液晶化合物は、ハロゲン基を有する第１芳香環と、ハロゲン基を有し、第１結合を介して第１芳香環に結合した第２芳香環と、脂肪族基を有し、第２結合を介して第２芳香環に結合した第３芳香環とを含む。第２液晶化合物は、第１芳香環と、第２芳香環と、脂肪族基を有し、第３結合を介して第２芳香環に結合した第１脂環式基とを含む。第３液晶化合物は、第４芳香環と、第４結合を介して第４芳香環に結合した第５芳香環と、脂肪族基を有し、第５結合を介して第４芳香環に結合した第２脂環式基と、脂肪族基を有し、第６結合を介して第５芳香環に結合した第３脂環式基とを含む。【選択図】なし
