An organic EL display includes an organic material, a gas barrier layer on the member, and an organic EL unit on the gas barrier layer. The gas barrier layer comprises AlxTiyOz, wherein Al represents aluminum, Ti represents titanium, O represents oxygen, x represents the ratio of atoms of Al, y represents the ratio of atoms of Ti, and z represents the ratio of atoms of O. A Ti-atom ratio of the gas barrier layer is given in the units of atom % and defined by the following equation: Ti-atom ratio={y/(x+y)}·100. The gas barrier layer has a first portion at an interface with the member and a second portion at an interface with the organic EL unit. The Ti-atom ratio of the first portion is 0 atom %. The Ti-atom ratio of the second portion is greater than or equal to 10 atom %.
