Patent ID: 8547014

Claim:
An organic EL device comprising an organic EL element that includes an anode having a reflective face, a cathode having a semi-transmissive reflective layer, and a functional layer, which is pinched between the anode and the cathode so that the cathode is in contact with the functional layer and at least one partition wall portion, and includes at least an organic light emitting layer, and configures a color pixel that implements light emission corresponding to at least a red color, wherein the color pixel configured by the organic EL element forms an optical resonator between the reflective face of the anode and the semi-transmissive reflective layer of the cathode, wherein the color pixel corresponding to the red color has a film thickness profile of the functional layer in a concave shape in which the center portion is relatively thin, and the periphery portion is relatively thick, and the film thickness R(a) of the peripheral portion of the concave-shaped functional layer satisfies equations (1) and (2) relating to the length d 1 of a resonance light path of the optical resonator, 2 d 1= m λ+(θ an *λ)/2π+(θ ca *λ)/2π equation (1): here, m is an integer, λ is a peak wavelength of the spectrum of light desired to be emitted, θan is the amount of phase shift in the case of reflection from the anode side, and θca is the amount of phase shift in the case of reflection from the cathode side; 0.9 d 1≦ R ( a )≦1.1 d 1, and equation (2): wherein the organic EL elements configure color pixels that implement light emission corresponding to at least the red color and the blue color, wherein the color pixel corresponding to the blue color has a film thickness profile of the functional layer in a convex shape in which the center portion is relatively thick, and the periphery portion is relatively thin.
