摘要： This organic EL device (100) has a substrate (1), a drive circuit layer (2), a first inorganic protective layer (2Pa), an organic planarizing layer (2Pb), an organic EL element layer (3), and a TFE structure (10). The TFE structure has a first inorganic barrier layer (12), an organic barrier layer (14), and a second inorganic barrier layer (16). When viewed from a normal line of the substrate, the organic planarizing layer is formed within a region where the first inorganic protective layer is formed, while an organic EL element is disposed within a region where the organic planarizing layer is formed. The TFE structure has an exterior edge which intersects with a lead-out line (32) and which is situated between an exterior edge of the organic planarizing layer and an exterior edge of the first inorganic protective layer. In a portion where the first inorganic protective layer and the first inorganic barrier layer are in direct contact with each other on the lead-out line, the first inorganic barrier layer has, in a cross-section parallel to the line width direction of the lead-out line, a lateral face that is configured to have a taper angle θ (12) of less than 90°. The organic planarizing layer has a surface that is not more than 50 nm in arithmetic average roughness Ra.

摘要： Provided is a display substrate including a base substrate, a plurality of pixel units, at least one first power line, a barrier structure, an adapting structure, a cathode layer and a first organic pattern. By covering at least part of the second side face of the adapting structure with the first organic pattern, the risk of the second side face of the adapting structure being eroded by moisture or oxygen due to the etching defects can be reduced.
