Display device and method of manufacturing display device
View Patent ↗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 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, 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, 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.
2. The display device according to claim 1 , wherein
the bank portion is located on both sides with respect to the protective coating in the second direction.
3. The display device according to claim 1 , 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
the bending region includes a base material, a wiring line provided on the display surface side of the base material, and an insulating film covering the wiring line, and
the bank portion is formed apart from the insulating film in the second direction.
5. The display device according to claim 4 , wherein
a groove is formed between the insulating film and the bank portion.
6. The display device according to claim 4 , wherein
the bank portion is formed of the same material as the insulating film.
7. The display device according to claim 4 , wherein
the protective coating covers the whole of the insulating film in the second direction.
8. The display device according to claim 1 , wherein
an outer edge of the protective coating is in contact with the bank portion.
9. The display device according to claim 1 , further comprising a rear surface film including a first film portion attached to the rear surface side of the display region and a second film portion attached to the rear surface side of the terminal region.
10. The display device according to claim 1 , further comprising a spacer interposed between the display region and the terminal region and in contact with the rear surface side of the bending region.
