Abstract
A display device includes a flexible substrate including a display area on which a plurality of pixels are disposed, a flexible film, and a photo-curable adhesive member for bonding the flexible substrate and the flexible film together. The photo-curable adhesive member includes a soft area and a cured area having higher hardness than the soft area.
Claims20
A display device comprising:
- a flexible substrate including a display area on which a plurality of pixels are disposed, a frame area including a bent area in which the flexible substrate is bent, and a terminal area along an edge of the flexible substrate;
- a flexible film;
- and
- a photo-curable adhesive member for bonding the flexible substrate and the flexible film together, wherein
- the bent area is between the display area and the terminal area,
- the photo-curable adhesive member includes a soft area and a hard area having higher hardness than the soft area,
- the hard area includes a first hard area which overlaps with the bent area and which does not overlap with the display area, and a second hard area which overlaps with the terminal area, and
- the first hard area and the second hard area are apart from each other.
