Self-luminous display panel and self-luminous display panel manufacturing method

A self-luminous display panel in which self-luminous elements are arranged on a plane, wherein

• each of the self-luminous elements comprises:
• a pair of electrodes disposed facing each other, an electrode of the pair of electrodes including a metal layer;
• functional layers including a light emitting layer, disposed between the pair of electrodes;
• and
• a sealing layer that covers the pair of electrodes and the functional layers from a direction, wherein
• the self-luminous elements include a repaired self-luminous element,
• the repaired self-luminous element further comprises:
• a foreign object among the functional layers, wherein
• the electrode including the metal layer has a high resistance portion that is a portion of the electrode including the metal layer that contains the foreign object, in plan view, and has a thickened portion of the metal layer at an outer edge, in plan view, of the high resistance portion.

A method of manufacturing a self-luminous display panel in which self-luminous elements are arranged on a plane, comprising:

• a process of forming the self-luminous elements on a substrate surface;
• a process of driving the self-luminous elements to detect an abnormal self-luminous element;
• and
• a process of repairing the abnormal self-luminous element, wherein
• the process of forming the self-luminous elements comprises:
• a sub-process of forming a pair of electrodes disposed facing each other, an electrode of the pair of electrodes including a metal layer;
• a sub-process of forming functional layers including a light emitting layer disposed between the pair of electrodes;
• and
• a sub-process of forming a sealing layer that covers the pair of electrodes and the functional layers, wherein
• the process of repairing the abnormal self-luminous element comprises:
• a process of detecting a position of a foreign object in the abnormal self-luminous element;
• and
• a process of forming a high resistance portion in the electrode including the metal layer in the abnormal self-luminous element, where the high resistance portion, in plan view, surrounds an area containing the foreign object, wherein
• in the process of forming the high resistance portion, a thickened portion of the metal layer close to an outer edge of the high resistance portion is formed.
