Abstract

The display device includes: a flexible display panel including a display portion in which scanning lines and signal lines cross each other; a supporting portion for supporting an end portion of the flexible display panel; a signal line driver circuit for outputting a signal to the signal line, which is provided for the supporting portion; and a scanning line driver circuit for outputting a signal to the scanning line, which is provided for a flexible surface of the display panel in a direction which is perpendicular or substantially perpendicular to the supporting portion.

Claims (55)

1. A display device comprising:

a first resin;

a first insulating layer over the first resin;

a semiconductor layer over the first insulating layer;

a second insulating layer over the semiconductor layer;

a first gate electrode layer over the second insulating layer;

a first electrode layer of a first light-emitting element over the first gate electrode layer;

a second electrode layer of the first light-emitting element over the first electrode layer of the first light-emitting element with an electroluminescent layer of the first light-emitting element provided therebetween; and

a second resin over the second electrode layer of the first light-emitting element,

wherein the display device further comprises:

a scanning line driver circuit comprising a first region located between the first resin and the second resin; and

a signal line driver circuit comprising a second region which is not located between the first resin and the second resin,

wherein the display device is configured to bend in a third region and a fourth region,

wherein the third region is provided between a fifth region in which the first resin and the second resin sandwich the first light-emitting element and a sixth region in which the first resin and the second resin sandwich a second light-emitting element, and

wherein the fourth region is provided between the fifth region in which the first resin and the second resin sandwich the first light-emitting element and a seventh region in which the first resin overlaps with the signal line driver circuit.

2. The display device according to claim 1 ,
