PROBLEM TO BE SOLVED: To improve the image quality of a display device.SOLUTION: A display panel is provided with a panel substrate and a film. In the display panel, a plurality of light emitting elements is provided on the panel substrate. In the display panel, the film is made of a material having a predetermined refractive index. A thickness of the film is determined according to: a substrate end distance from the light emitting element nearest to an end of the panel substrate among the plurality of light emitting elements to the end of the panel substrate; a view angle formed by the visual field with brightness of the light satisfying a certain level; and the refractive index. 【課題】表示装置において画質を向上させる。【解決手段】表示パネルは、パネル基板とフィルムとを具備する。この表示パネルにおいて、パネル基板には、光を発する複数の発光素子が設けられる。また、表示パネルにおいて、フィルムは、所定の屈折率の部材からなり、複数の発光素子のうちパネル基板の端部に最も近い発光素子から端部までの基板端距離と前記光の明るさが一定の基準を満たす視野のなす角度である視野角と前記屈折率とに応じた膜厚のフィルムである。【選択図】図４
