Electroluminescence display device

摘要

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.

主权项

1. An EL display device comprising:
a substrate; a pixel including a lower electrode on the substrate; another pixel including another lower electrode on the substrate and being adjacent to the pixel in a horizontal direction in a cross-sectional view; a pixel separation film provided on the substrate and having a part which has a length in the horizontal direction and is located on a boundary between the pixel and the another pixel, an upper electrode located above the lower electrode and the another lower electrode; and a patterned auxiliary electrode provided on the upper electrode and having another length in the horizontal direction, wherein the patterned auxiliary electrode is located on the boundary, wherein the pixel has an area which does not overlap the patterned auxiliary electrode, the another pixel has another area which does not overlap the patterned auxiliary electrode, the patterned auxiliary electrode covers the part of the pixel separation film, and the another length is longer than the length.
