To provide a display device that can improve the uniformity of luminance.SOLUTION: A display device includes a liquid crystal layer LC disposed between a first substrate SUB1 and a second substrate SUB2 and including striped polymer 31 and a liquid crystal molecule 32. The liquid crystal layer LC includes a first region LCA closer to a first side surface 20C, and a second region LCB close to a second side surface 20D and existing between the second side surface 20D and the first region LCA. In a state where voltage is not applied to the liquid crystal layer LC, a first intersection angle between a first director of the liquid crystal molecule 32 in the first region LCA and a first extension axis of the polymer 31 is different from a second intersection angle between a second director of the liquid crystal molecule 32 in the second region LCB and a second extension axis of the polymer 31.SELECTED DRAWING: Figure 1 【課題】輝度の均一性を向上することが可能な表示装置を提供する。【解決手段】第１基板ＳＵＢ１と第２基板ＳＵＢ２との間に配置され、筋状のポリマー３１と、液晶分子３２とを含む液晶層ＬＣと、を備え、液晶層ＬＣは、第１側面２０Ｃに近接する側の第１領域ＬＣＡと、第２側面２０Ｄに近接し、第２側面２０Ｄと第１領域ＬＣＡとの間に位置する第２領域ＬＣＢと、を有し、液晶層ＬＣに電圧が印加されていない状態において、第１領域ＬＣＡに含まれる液晶分子３２の第１ダイレクタとポリマー３１の第１延伸軸との第１交差角は、第２領域ＬＣＢに含まれる液晶分子３２の第２ダイレクタとポリマー３１の第２延伸軸との第２交差角とは異なる、表示装置。【選択図】図１
