To provide a display device capable of having higher display quality.SOLUTION: A display device according an embodiment includes a first substrate, a second substrate, a liquid crystal layer held between the first substrate and the second substrate and containing stripe-shaped polymer and a first liquid crystal molecule with responsiveness to an electric field, a light source that emits light propagating in the first substrate, the second substrate, and the liquid crystal layer, and a transparent film disposed on at least one of an emission surface of the light emitted from the first substrate side and an emission surface of the light emitted from the second substrate side and containing a second liquid crystal molecule without responsiveness to the electric field. The second liquid crystal molecule has a large tilt angle to a horizontal plane of the transparent film in a first region away from the light source, and in a second region between the light source and the first region, has a tilt angle to the horizontal plane of the transparent film smaller than that of the first region.SELECTED DRAWING: Figure 6 【課題】表示品位を向上させることが可能な表示装置を提供すること。【解決手段】実施形態に係る表示装置は、第１基板と、第２基板と、第１基板と第２基板との間に保持され、筋状のポリマーと、電界に対する応答性を有する第１液晶分子とを含む液晶層と、第１基板、第２基板および液晶層内を伝播する光を放つ光源と、第１基板側から出射される光の出射面、および、第２基板側から出射される光の出射面のうちの少なくとも一方に配置され、電界に対する応答性を有さない第２液晶分子を含む透明フィルムと、を備え、第２液晶分子は、光源から離れた第１領域においては透明フィルムの水平面に対する傾斜角が大きく、光源と第１領域との間に位置する第２領域においては透明フィルムの水平面に対する傾斜角が第１領域の傾斜角より小さい。【選択図】 図６
