  • Publication number: 20220149314
    Abstract: A self-luminous display panel 10 in which self-luminous elements 2 are arranged on a plane, wherein each of the self-luminous elements includes: a pair of electrodes 13, 20 disposed facing each other, an electrode of the pair of electrodes including a metal layer 20A; functional layers 15, 16, 17, 18, 19 including a light emitting layer 17, disposed between the pair of electrodes; and a sealing layer 21 that covers the pair of electrodes and the functional layers from a direction. The self-luminous elements include a repaired self-luminous element 2?. The repaired self-luminous element includes a foreign object FO among the functional layers. The electrode including the metal layer has a high resistance portion 201 surrounding, in plan view, an area containing the foreign object, and has a thickened portion 202 of the metal layer at an outer edge, in plan view, of the high resistance portion.

  • Patent number: 5989088
    Abstract: The present invention provides a manufacturing method of a flat-panel display unit and a carrier therefor which make it unnecessary to implement alignment in each step, except for alignment which require higher precision, by performing the alignment in advance in the pre-stage of a series of steps. The present invention also provides a manufacturing method of a flat-panel display unit which allows alignment with accuracy of about 50 to 100 .mu.m to be performed simply, reliably and quickly. According to the inventive manufacturing method, a display panel is mounted non-shiftably on the carrier and while being mounted thereon, is then carried between processing machines and is processed by the processing machines. In mounting the display panel on the carrier, it is aligned with the carrier in advance by visually aligning alignment marks thereof.
