OG exemplary drawing
 
1. A display device comprising:
a display panel; and
a first conductive layer,
wherein the display panel comprises a second conductive layer, a first flexible substrate over the second conductive layer, a transistor over the first flexible substrate, a light-emitting element over the first flexible substrate, and a second flexible substrate over the light-emitting element,
wherein light emitted by the light-emitting element is extracted from the first flexible substrate side, so that an image is displayed,
wherein the first conductive layer comprises a portion which overlaps with the light-emitting element with the second conductive layer provided therebetween,
wherein the second conductive layer comprises a portion which overlaps with the transistor with the first flexible substrate provided therebetween,
wherein the second flexible substrate comprises a glass layer, a bonding layer, and a resin layer, which are stacked in this order from a side of the light-emitting element,
wherein a thickness of the glass layer is greater than or equal to 25 μm and less than or equal to 100 μm,
wherein a thickness of the resin layer is greater than or equal to 10 μm and less than or equal to 200 μm,
wherein a state of a display surface of the display panel is changeable between a flat state and a bent state,
wherein when the display surface is bent, a shape of the first conductive layer is not changed, and
wherein when the display surface is bent, the second conductive layer comprises a portion that is convexly curved along the bent display surface of the display panel and is not in contact with the first conductive layer.
