Patent ID: 8390549

Claim:
An organic luminescent display device comprising multiple organic luminescent elements having different luminescent colors so as to emit one of red, green and blue lights, wherein: the organic luminescent elements each have a lower electrode, an upper electrode provided on the lower electrode, and a luminescent layer provided between the lower electrode and the upper electrode; wherein a dielectric alternate laminated film obtained by alternately laminating dielectric films made of at least two kinds of materials is provided on the upper electrode of the multiple organic luminescent elements; wherein a view angle-controlling layer is provided on the dielectric alternate laminated film; wherein the dielectric alternate laminated film include a dielectric film made of a first dielectric material and another dielectric film made of a second dielectric material having a lower refractive index than a refractive index of the first dielectric material; and wherein the dielectric alternate laminated film has at least one first laminated film obtained by superimposing a layer made of the first dielectric material having an optical length equal to a quarter of a center wavelength λ G of green light emission and a layer made of the second dielectric material having an optical length equal to a quarter of the center wavelength λ G of the green light emission, and at least one second laminated film obtained by superimposing a layer made of a third dielectric material having one of an optical length equal to a center wavelength λ B of blue light emission and an optical length equal to three quarters of a center wavelength λ R of red light emission, and a layer made of a fourth dielectric material having one of an optical length equal to three quarters of the center wavelength λ B of the blue light emission and an optical length equal to one half of the center wavelength λ R of the red light emission.
