  • Publication number: 20200176699
    Abstract: Disclosed is an electroluminescence display device. The electroluminescence display device includes a flexible substrate, a first metal layer, an inorganic material layer, a recessed portion, a second metal layer, and an organic material layer. The flexible substrate has a bending axis. The first metal layer is disposed on the flexible substrate to be parallel with the bending axis. The inorganic material layer is stacked on the first metal layer. The recessed portion is disposed in the inorganic material layer to be parallel to the bending axis and exposes the first metal layer. The second metal layer extends in parallel to the bending axis, covers the recessed portion, and is in contact with the first metal layer. The organic material layer covers the inorganic material layer and the second metal layer.

  • Publication number: 20190165076
    Abstract: A flexible display device is disclosed, which may prevent a crack from being generated even though a bending area is folded and prevents a gate driving circuit from being damaged and prevents a gate shift clock line from being shorted even though the crack is generated. The flexible display device comprises a substrate including a display area for displaying an image, a non-display area surrounding the display area, and a bending area. A pixel for displaying an image, an inorganic film for covering the pixel and a first organic film for covering the inorganic film are arranged on an area corresponding to the display area of the bending area, and the first organic film is arranged on an area corresponding to the non-display area of the bending area.
