PROBLEM TO BE SOLVED: To provide a display device capable of preventing color mixture by transmission of light emitted from an organic EL element to an adjacent pixel, and thereby allowing high-precision display. SOLUTION: This display device 1 is composed by arranging, on a substrate 10, a plurality of organic electroluminescent elements EL each formed by sandwiching an organic layer 22 between a lower electrode 21 and an upper electrode 23, and is characterized by comprising: the lower electrodes 21 patterned and formed on respective pixels 10r, 10g and 10b on the substrate 10; insulation films 17 formed between the lower electrodes 21; an organic layer 22 arranged in a state contacting the lower electrodes 21 and the insulation films 17 to cover them, and having a refraction index n1 nearly equal to a refraction index n2 of the insulation film 17; and the upper electrodes 23 sandwiching the organic layer 22 between the lower electrodes 21 and themselves for extracting emission light generated in the organic layer 22 therefrom.
