Abstract
A curved display device including a display area and a non-display area is provided. The curved display device includes a first direction area configured to maintain a flat state and a bending area connected to the first direction area. A thin film transistor (TFT) layer, a passivation layer, a sealing layer, and an upper film are provided on a base substrate in an area where the display area overlaps the bending area, and the sealing layer and the upper film extend to an area where the non-display area overlaps the bending area.
Claims19
A display device comprising:
- a substrate having a flat area and a bending area connected to the flat area;
- a first thin film transistor (TFT) layer on the substrate;
- a light emitting diode layer on the first TFT layer;
- a passivation layer on the light emitting diode layer;
- an upper film on the passivation layer, the upper film extending to a first area where a non-display area overlaps the bending area;
- and
- a crack transfer preventing part in the first area,
- a second TFT layer facing the first TFT layer with the crack transfer preventing part therebetween;
- wherein the passivation layer covers the first TFT layer, the second TFT layer, and the crack transfer preventing part.
A display device comprising:
- a substrate having a flat area and a bending area connected to the flat area;
- a thin film transistor (TFT) layer including a plurality of layers on the substrate;
- a light emitting diode layer on the TFT layer;
- and
- a passivation layer on the light emitting diode layer,
- wherein the TFT layer includes a first TFT layer in an area where a non-display area overlaps the bending area and a second TFT layer in an area where a display area overlaps the bending area, and the first TFT layer is separated from the second TFT layer, in order to prevent a crack in the non-display area from being transferred to the display area.
A display device comprising:
- a substrate having a flat area and a bending area connected to the flat area;
- a thin film transistor (TFT) layer including a plurality of layers on the substrate;
- a light emitting diode layer on the TFT layer;
- and
- a passivation layer on the light emitting diode layer, extending to a first area where a non-display area overlaps the bending area and a second area where a display area overlaps the bending area,
- wherein a top of a first portion of the passivation layer provided in the first area is lower than each of a top of a second portion of the passivation layer provided in the first area and a top of the passivation layer provided in the second area, and
- wherein a crack transfer preventing part is provided in an area corresponding to the first portion of the passivation layer.
A display device comprising:
- a substrate having a flat area and a bending area connected to the flat area;
- a thin film transistor (TFT) layer including a protective layer on the substrate;
- a light emitting diode layer on the TFT layer;
- a moisture preventing layer on the light emitting diode layer to prevent moisture from penetrating into the light emitting diode layer;
- an upper film on the moisture preventing layer, extending to an area where a non-display area overlaps the bending area;
- and
- a crack transfer preventing part provided in the area, covered by the moisture preventing layer.
