PROBLEM TO BE SOLVED: To improve contrast of a light-emitting element and a display device using it. SOLUTION: The light-emitting element such as an organic electroluminescent element is provided with a first electrode 20 composed of a transparent electrode at a light-emitting side and a second electrode 22 formed at a back face side of the element so as to be opposed to the first electrode 20 with a light-emitting layer in between. The second electrode 22 is to be a semi-transparent electrode, at further back side of which 22, an anti-reflection layer 46 having a low light reflection rate is formed. Light incident from outside the element transmitting the transparent electrode is made transmitted without being reflected at the semi-transparent second electrode 22, and is made absorbed at the anti-reflection layer 46, so that reflection of outside light on the surface of a back plate is restrained and contrast is enabled to be improved. The second electrode 22 may exert a semi-transparency by making a metal material a thin film or fitting itself with an opening. COPYRIGHT: (C)2005,JPO&NCIPI
