To provide a display device in which differences in display quality depending on a viewing angle are improved while reducing a reflectance by external light.SOLUTION: A display device DS includes a display panel DP including an organic electroluminescent element and a color filter member CFP disposed on the display panel DP and comprising a plurality of color filter portions separated from one another on a plane. At least one color filter portion of the plurality of color filter portions contains a scattering agent having an average diameter of 50 nm or more and 500 nm or less. The display device shows improved display quality by reducing color differences depending on a viewing angle while reducing reflection by external light. The color filter member CFP may comprise a first color filter portion CCF1 that transmits light in a first wavelength region and a second color filter portion CCF2 that transmits light in a second wavelength region different from the first wavelength region.SELECTED DRAWING: Figure 4 【課題】外部光による反射率を減少させながら、視野角による表示品質の差を改善した表示装置を提供する。【解決手段】表示装置ＤＳは、有機電界発光素子を含む表示パネルＤＰと、表示パネルＤＰの上に配置され、平面上において互いに離隔した複数のカラーフィルタ部を含むカラーフィルタ部材ＣＦＰと、を含み、複数のカラーフィルタ部のうち少なくとも一つのカラーフィルタ部は、平均直径が５０ｎｍ以上５００ｎｍ以下の散乱剤を含み、外部光による反射を低減させながらも視野角による色差を減らすことで、改善された表示品質を示す。カラーフィルタ部材ＣＦＰは、第１波長領域の光を透過させる第１カラーフィルタ部ＣＣＦ１と、第１波長領域とは異なる第２波長領域の光を透過させる第２カラーフィルタ部ＣＣＦ２と、を含んでもよい。【選択図】図４
