Abstract
An organic electroluminescence display device 100 comprises a color modulating member 2 including a plurality of shading layers 21 and a plurality of color modulating layers 22, the layers 21 and 22 being arranged in a planar and discrete manner, an organic EL electroluminescent member 3 including a plurality of organic EL elements arranged in a planar and discrete manner at a site corresponding to the color modulating layers 22, and a transparent medium 1 sandwiched between the color modulating member 2 and the organic EL electroluminescent member 3, wherein the relation d2≧d1 is satisfied, with d1 being a distance between the color modulating member 2 and the organic EL electroluminescent member 3, and d2 being a width of the shading layer. A practical organic EL display device is thus provided which has an excellent viewing angle property as well as an excellent visuality and which can prevent occurrence of color-shift (color mixing) and blot.
