Beschreibung
Zusammenfassung:	An objective of the present invention is to provide an optical laminate capable of suppressing corrosion of a metal layer and a liquid crystal display device including the same. The optical laminate comprises an optical film, an adhesive layer and a metal layer in this order, wherein the metal layer is a metal wiring layer, the adhesive layer is composed of an adhesive composition comprising a (meth)acrylic resin (A), an isocyanate-based crosslinking agent (B), a silane compound (C), and an ionic compound (D) represented by chemical formula: M^+X^-(M^+represents an inorganic cation and X^-represents a fluorine atom-containing anion) and the adhesive composition comprises 0.01 to 2.5 parts by weight of the isocyanate-based crosslinking agent (B), 0.01 to 10 parts by weight of the silane compound (C) and 0.2 to 8 parts by weight of the ionic compound (D) based on 100 parts by weight of the (meth)acrylic resin (A). 본 발명은, 광학 필름과, 점착제층과, 금속층을 이 순서로 포함하고, 금속층은, 금속 배선층이며, 점착제층은, (메트)아크릴계 수지(A), 이소시아네이트계 가교제(B), 실란 화합물(C) 및 식: M+ X-(M+는 무기 양이온, X-는 불소 원자 함유 음이온을 나타냄)로 표시되는 이온성 화합물(D)을 포함하는 점착제 조성물로 구성되고, 점착제 조성물은, (메트)아크릴계 수지(A) 100 중량부에 대하여, 이소시아네이트계 가교제(B)를 0.01∼2.5 중량부, 실란 화합물(C)을 0.01∼10 중량부 및 이온성 화합물(D)을 0.2∼8 중량부 함유하는 광학 적층체, 및 이것을 포함하는 액정 표시 장치를 제공하는 것을 목적으로 한다.
