ELECTROLUMINESCENT DEVICE HAVING AN IMPROVED CONTRAST

摘要

This invention relates to an electroluminescent display device (10) comprising a 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 ( lambda 1) and said second element (15b) is arranged to emit light at a second wavelength ( lambda 2). Furthermore, a first absorbing layer (18), arranged to absorb light of said second wavelength ( lambda 2) and transmit light of said first wavelength ( lambda 1), is arranged between said first light-emitting element (12) and said front substrate (11).
