A new organic EL display panel includes transparent electrodes , an insulating layer , an organic luminous layer and backside electrodes successively laid on a transparent substrate . The insulating layer is converted from a positive novolac, negative cyclized rubber or chemical amplified photoresist layer shaped to a grate pattern, by baking treatment to remove water and a solvent from the photoresist layer. Electric resistance of the insulating layer is good enough to inhibit leakage of an electric current between the electrodes and . The EL display panel reproduces a distinct image over a long term without growth of dark spots.
