ELECTROLUMINESCENT DEVICE HAVING AN IMPROVED CONTRAST

摘要

This invention relates to an electroluminescent display device (10) comprising D transmissive front substrate (11) and at least a first and a second light-emitting element (12, 15b), wherein said first element (12) is arranged to emit light at a first wavelength (lambda1) and said second element (15b) is arranged to emit light at a second wavelength (lambda2). Furthermore, a first absorbing layer (18), arranged to absorb light of said second wavelength (lambda2) and transmit light of said first wavelength (lambda1) is arranged between said first light-emitting element (12) and said front substrate (11).
