Window assembly comprising a protective film having a masking member and method for manufacturing display device
A window assembly includes a cover member including a front surface and a rear surface opposite to the front surface, and a protective film assembly disposed on the front surface or the rear surface of the cover member, where the protective film assembly includes a base part including a first portion overlapping the cover member, and a second portion protruding from the first portion, an adhesive layer disposed on the base part and between the cover member and the base part, and a masking member disposed on the adhesive layer to overlap at least a portion of the second portion, where the masking member includes a material derived from a curable ink composition.
1 . A window assembly comprising:
a cover member including a front surface and a rear surface opposite to the front surface; and
a protective film assembly disposed on at least one selected from the front surface and the rear surface of the cover member,
wherein the protective film assembly includes:
a base part including a first portion overlapping the cover member, and a second portion protruding from the first portion, wherein the second portion does not overlap the cover member on a plane;
an adhesive layer disposed on the base part and between the cover member and the base part; and
a masking member disposed on the adhesive layer to overlap at least a portion of the second portion, wherein the masking member comprises a material derived from a curable ink composition.
2 . The window assembly of claim 1 , wherein the curable ink composition comprises an acrylic resin.
3 . The window assembly of claim 2 , wherein the curable ink composition further comprises a photoinitiator.
4 . The window assembly of claim 1 , wherein the masking member has a thickness in a range of about 3 micrometers to about 20 micrometers.
5 . The window assembly of claim 1 , wherein the masking member is spaced apart from the cover member by a first gap, wherein the first gap is about 0.2 millimeter or less.
6 . The window assembly of claim 1 , wherein the adhesive layer comprises:
a first adhesive surface adjacent to the cover member; and
a second adhesive surface adjacent to the base part,
wherein the masking member is disposed on the first adhesive surface.
7 . The window assembly of claim 1 , wherein the adhesive layer is in contact with each of the base part and the cover member.
8 . The window assembly of claim 1 , wherein the adhesive layer is defined by a single layer between the masking member and the base part.
9 . The window assembly of claim 1 , wherein the adhesive layer comprises a first adhesive portion overlapping the first portion of the base part, and a second adhesive portion overlapping the second portion of the base part,
wherein the masking member is disposed on the second adhesive portion.
10 . The window assembly of claim 9 , wherein one side surface of the second portion, one side surface of the second adhesive portion, and one side surface of the masking member define a single aligned side surface of the window assembly.
11 . The window assembly of claim 1 , wherein the protective film assembly includes:
a first protective film assembly disposed on the rear surface of the cover member; and
a second protective film assembly disposed on the front surface of the cover member.
12 . The window assembly of claim 11 , wherein:
the first protective film assembly comprises a first masking member; and
the second protective film assembly comprises a second masking member,
wherein the first masking member and the second masking member do not overlap each other on a plane.
13 . A window assembly comprising:
a cover member including a front surface and a rear surface opposite to the front surface; and
a protective film assembly disposed on at least one selected from the front surface and the rear surface of the cover member,
wherein the protective film assembly includes:
a base part including a first portion overlapping the cover member, and a second portion protruding from the first portion, wherein the second portion does not overlap the cover member on a plane;
an adhesive layer disposed on the base part, wherein at least a portion of the adhesive layer is disposed between the cover member and the base part; and
a masking member disposed on the adhesive layer to overlap at least a portion of the second portion, wherein the masking member comprises a cured acrylic resin.
14 . A method for manufacturing a display device, the method comprising:
preparing a cover member;
preparing a display module; and
coupling the cover member to the display module,
wherein the preparing the cover member includes:
forming a protective film assembly; and
adhering the protective film assembly on at least one surface of the cover member,
wherein the forming the protective film assembly includes:
preparing a base part including a first portion overlapping the cover member, and a second portion protruding from the first portion;
forming an adhesive layer on the base part;
forming a preliminary masking member on the adhesive layer by providing a curable ink composition to overlap the second portion; and
forming a masking member by curing the preliminary masking member.
15 . The method of claim 14 , wherein the preparing the cover member further includes removing the protective film assembly adhered to the at least one surface of the cover member.
16 . The method of claim 14 , wherein the curable ink composition comprises an acrylic resin.
17 . The method of claim 16 , wherein
the curable ink composition further comprises a photoinitiator, and
in the curing the preliminary masking member, the preliminary masking member is irradiated with ultraviolet rays.
18 . The method of claim 16 , wherein in the curing of the preliminary masking member, the preliminary masking member is moisture-cured.
19 . The method of claim 14 , wherein the curing the preliminary masking member is performed at about 60° C. or less.
