ABSTRACT:
A transparent first substrate and a second substrate of an organic multicolor emission and display device are positioned opposite to each other with a predetermined clearance and sealed with a gap material that performs desiccating a surrounding atmosphere. The gap material advantageously has different void fractions between in an inner portion facing a sealed space within the device and in an outer portion facing an external atmosphere.Featuring the above structure, an organic multicolor emission and display device of color conversion system has been provided that maintains stable light emitting performance for a long period and exhibits excellent visibility angle characteristic.
