PROBLEM TO BE SOLVED: To reduce an unfavorable effect of scrap and dust at positioning a mask. SOLUTION: The active matrix type organic electroluminescent panel is composed of a plurality of organic EL elements 50 each having an organic layer 60 at least containing an organic light-emitting material between a lower side individual electrode 52 and an upside electrode 54 which are patterned for every pixel, formed on the upper part of a substrate. An end covering insulation layer (32a) is formed so as to cover the peripheral end of the lower side individual electrode 52, and a mask supporting insulation layer supporting an evaporation mask for forming an organic layer thicker than the end covering insulation layer is formed at a further outer peripheral side of the end covering insulation layer. The organic layer 60 is formed on an area extending to the outside of a boundary between the the end covering insulation layer (32b) and the lower side individual electrode 52 to the inside of an area in which the mask supporting insulation layer (32b) is formed, and individually patterned for every pixel. This prevents the organic layer from being damaged and dust from being generated caused by the touch of the organic layer with the mask, when the mask is supported by the mask supporting layer for positioning.
