Title:
ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/109964
Kind Code:
A1
Abstract:
In a first organic electroluminescence element (10), an optical distance between a first light reflecting means (12) and a second light reflecting means (14) is set to select light of a first color. In a second organic electroluminescence element (20), the optical distance between the first light reflecting means (12) and the second light reflecting means (14) is set to select light of a second color. In a third organic electroluminescence element (30), the optical distance between the first light reflecting means (12) and the second light reflecting means (14) is set to select light of a third color. In an organic electroluminescence display device, an average reflectance ratio of the first light reflecting means (12) for a wavelength of 400nm-700nm is 65% or more.
