Abstract:
An organic EL display device includes a reflective electrode and a transparent electrode disposed facing each other with an organic EL layer interposed therebetween. The reflective electrode includes a reflective film and a protection film formed on the reflective film, and the protection film includes a frame-shaped portion surrounding the periphery of the organic EL layer and an opening surrounded by the frame-shaped portion. This improves the reflectivity of the reflective electrode while protecting the reflective electrode.
