摘要： An organic EL display device (100) disposed with a transparent medium (1) sandwiched between a color converting member (2) having a plurality of shading layers (21) and a plurality of color converting layers (22) alternately disposed on one surface and an organic EL light emitting member (3) comprising a plurality of organic EL elements (31) disposed on the surface in the position facing the color converting layers (22). The organic EL display device satisfies the relationship of a distance (d1) between the color converting member (2) and the organic EL light emitting member (3) and a width (d2) of the shading layers (21) that the distance is not longer than the width d2. Accordingly, a practicable organic EL display device which excels in characteristics of angle of view, can prevent the generation of chromatic aberration (color mixture) and bleeding and at the same time which excels in color discrimination.

摘要： A color conversion layer is provided which is capable of converting light from an emitting medium effectively to light containing a ray having a longer wavelength and exhibits less deterioration so as to have a long lifetime. The color conversion layer comprising a fluorescent medium for converting light emitted from an emitting medium to light having a longer wavelength, and having a haze value of 50% to 95%. The color conversion layer can be made thin, since the layer can efficiently convert the color of light from an emitting medium. The processibility such as patterning thereof is then improved.
