Display device and method of manufacturing display device
A display device includes a display panel including a display region, a terminal region provided with a terminal, and a bending region located between the display region and the terminal region and capable of bending, the terminal region being located on a rear surface side opposite to a display surface side with respect to the display region based on the bending region bent and a protective coating provided on the display surface side of the bending region. When a direction in which the display region, the bending region, and the terminal region are arranged is defined as a first direction and a direction crossing the first direction is defined as a second direction, the bending region includes a bank portion located in the second direction with respect to the protective coating, projecting to the display surface side, and extending in the first direction.
1. A display device comprising:
a display panel including a flexible substrate, a display region on a first surface of the flexible substrate, a terminal region on the first surface of the flexible substrate, and a bending region between the display region and the terminal region; and
a resin layer covering on the first surface of the flexible substrate at the bending region, wherein
the bending region includes a pair of bank portions,
one of the pair of bank portions is between a first edge of the flexible substrate and the resin layer in a planar view,
another one of the pair of bank portions is between a second edge of the flexible substrate and the resin layer in the planar view,
the resin layer is between the pair of bank portions in the planar view,
the resin layer is in contact with both of the pair of bank portions,
the resin layer is neither in contact with the first edge of the flexible substrate nor the second edge of the flexible substrate; wherein
the bending region includes a base material, a wiring line on the first surface of the flexible substrate, and an insulating film covering the wiring line, and
the bank portion is formed apart from the insulating film.
2. The display device according to claim 1 , wherein
a direction in which the display region, the bending region, and the terminal region are arranged is defined as a first direction and a direction crossing the first direction is defined as a second direction, and
each of the pair of bank portions extending in the first direction.
3. The display device according to claim 2 , wherein
the bank portion is formed over the whole of the bending region in the first direction.
4. The display device according to claim 1 , wherein
a groove is formed between the insulating film and the each of the pair of bank portions.
5. The display device according to claim 1 , wherein
the pair of bank portions are formed of the same material as the insulating film.
6. The display device according to claim 1 wherein
the resin layer covers the whole of the insulating film in the second direction.
7. The display device according to claim 1 , further comprising a rear surface film on a second surface of the flexible substrate, wherein
the rear surface film includes a first portion which overlaps with the display region, and a second portion which overlaps with the terminal region.
8. The display device according to claim 1 , further comprising a spacer, wherein
the terminal region is folded back at the bending region,
the spacer is interposed between the display region and the terminal region.
