ROLLABLE DISPLAY DEVICE
First Claim
1. A display device comprising:
- a frame; and
a flexible display unit configured to be wound into the frame, and comprising a transparent adhesive layer, the adhesive layer having a first surface and a second surface opposite to the first surface,wherein the adhesive layer is configured to adhere layers on the first surface and the second surface thereof to each other, andwherein a first elongation percentage of the adhesive layer in a first direction is greater than a second elongation percentage of the adhesive layer in a second direction crossing the first direction, the first direction being a direction along which the display unit is unwound from the frame.

14. A display device comprising a flexible display unit configured to be wound in a roll shape, the flexible display unit comprising:
-
a flexible substrate; a display layer on the flexible substrate; a thin-film encapsulation layer sealing the display layer; a functional layer on the thin-film encapsulation layer; and an adhesive layer between the thin-film encapsulation layer and the functional layer, the adhesive layer comprising a base and a plurality of modulus adjusting areas having a line shape in a region of the base, wherein the plurality of modulus adjusting areas are separated from each other along a first direction to form a stripe pattern, wherein the base and the plurality of modulus adjusting areas comprise a same material, and wherein a first modulus of the base is greater than a second modulus of the plurality of modulus adjusting areas. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
