Abstract:
1. An organic EL display device including a display panel which is formed by arranging pixels constituted of a plurality of organic EL elements on an active substrate in a matrix array, wherein the organic EL element is provided to the active substrate for every unit color pixel which is constituted of a plurality of sub pixels, and is constituted of one electrode in which a sub pixel opening is formed, an organic EL layer which is formed on one electrode, and a second electrode which is formed on the organic EL layer while covering the organic EL layer, and said sub pixel opening coordinated on a coordinated system, said coordinate system having an origin, a film forming center of an EL layer coordinated relative to said coordinate system, said sub pixel opening coordinated on a coordinate system, said coordinate system having an origin, a film forming center of an EL layer coordinated relative to said coordinate system, angles made between vectors indicative of misalignments of the film forming centers of respective organic EL layers relative to the centers of the sub pixel openings respectively at an arbitrary position on the display panel fall within an angle value of an angle value of 90°, wherein a measurement of said angle value is measured keeping the center of the sub pixel opening as the origin of the coordinate system of said measurement.
