  • Patent number: 10381599
    Abstract: A highly reliable light-emitting device is provided. Damage to an element due to externally applied physical power is suppressed. Alternatively, in a process of pressure-bonding of an FPC, damage to a resin and a wiring which are in contact with a flexible substrate due to heat is suppressed. A neutral plane at which stress-strain is not generated when a flexible light-emitting device including an organic EL element is deformed, is positioned in the vicinity of a transistor and the organic EL element. Alternatively, the hardness of the outermost surface of a light-emitting device is high. Alternatively, a substrate having a coefficient of thermal expansion of 10 ppm/K or lower is used as a substrate that overlaps with a terminal portion connected to an FPC.

  • Patent number: 10121986
    Abstract: A display apparatus includes a first conductive line positioned outside a display area of a substrate. A passivation layer covers a portion of the first conductive line. A second conductive line is positioned between the display area and the first conductive line, overlapping the first connection line and including a hole. The hole of the second conductive line overlaps one of at least one opening. A passivation layer is interposed between the second conductive line and a first connection line. Overlapping areas between the first and second conductive lines outside of the display area are decreased, and thus, an occurrence of a short circuit in the display apparatus is decreased.
