摘要： An organic EL panel includes first electrode, second electrode; organic light-emitting layer of each of RGB colors, and functional layer disposed between the first electrode and the light-emitting layer. The functional layers of RGB colors have the same film thickness. Film thickness of each of the functional layers of RG colors corresponds to a first local maximum of light-extraction efficiency of light before passing through a color filter, and film thickness of the functional layer of B color corresponds to a value of light-extraction efficiency smaller than a first local maximum of light-extraction efficiency of light before passing through a color filter. The light-emitting layers of RGB colors differ in film thickness, such that the functional layers of RGB colors have the film thickness. Accordingly, the light of each of RGB colors emitted externally after passing through the color filter exhibits a local maximum of light-extraction efficiency.
