US 2016/0111474 A1 · ELECTROLUMINESCENCE DISPLAY DEVICE

Abstract

There is provided an EL display device of a color filter system which obtains sufficient brightness and contrast while making it difficult to generate a color mixture even if pixels become fine. An EL display device 100 according to the present invention includes a first substrate 1, a circuit layer 2 formed on the first substrate 1, a color selection reflection layer 11 formed in an upper layer of the circuit layer 2, lower electrodes 5 formed in an upper layer of the color selection reflection layer 11, a white light emission EL layer 7 formed in an upper layer of the lower electrodes 5, an upper electrode 8 formed in an upper layer of the EL layer 7, and a sealing layer 9 formed in an upper layer of the upper electrode 8.
