An organic EL panel (light transmissive luminescent panel) is configured to have a display screen formed of a plurality of pixels with improved display performance by restricting stray light at the panel edge surface and enabling a high-grade color display by restricting the reduction of the mixing ratio of colors. The organic EL panel is of a light-transmissive type with organic EL elements formed on the panel substrate, The display screen is configured by a plurality of pixels which are organic EL elements, The right and left edge faces of the panel substrate or the sealing substrate are made to be light-absorbent or light non-transmissive, The light-emitting surface of the organic EL element is made in a horizontally elongated shape with a longitudinal direction orthogonal to a direction along the right and left edge faces,
