Claims18
A touch window comprising:
- a substrate;
- and
- an electrode part provided on the substrate and including an electrode layer and a pattern layer having a plurality of first sub-patterns and a plurality of second sub-patterns,
- wherein the electrode layer is provided only on the plurality of first sub-patterns,
- wherein the plurality of second sub-patterns are provided between the plurality of first sub-patterns,
- wherein a width of each first sub-pattern of the plurality of first sub-patterns is larger than a width of each second sub-pattern of the plurality of second sub patterns,
- wherein a retardation difference is 0.2% or less depending on an incident angle of light in the substrate,
- wherein the pattern layer comprises a photocurable resin composition comprising (a) urethane acrylate oligomer comprising one selected from the group consisting of polycarbonate polyol, polycaprolactone polyol, and combination thereof, (b) a monomer having a double bond, (c) a photoinitiator, and (d) a curing accelerator, and
- wherein the monomer having the double bond includes one selected from the group consisting of 1,4-butanediol dimethacrylate, dimethylaminoethyl methacrylate, 2-ethylhexyl methacrylate, iso-decyl methacrylate, glycidyl methacrylate, n-butyl methacrylate, hexyl methacrylate, decyl methacrylate, 1,6-hexanediol dimethacrylate, ethoxylated bisphenol-A dimethacrylate, t-butylaminoethyl methacrylate, isoamyl methacrylate, isobutyl methacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate, 1,3-butanediol dimethacrylate, and combination thereof.
