Document Type and Number:
WIPO Patent Application WO/2021/200734
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical laminate that is suitable for producing a self-luminous display device such as a mini/micro-LED display device in which light emission efficiency is increased and the anti-reflection function and contrast of metal wiring and the like are improved. This optical laminate 10 has a layered structure in which a first adhesive layer 1, a first substrate S, and a second adhesive layer 2 are layered in this order. The visible light transmittance T1 of the first adhesive layer 1 and the visible light transmittance T2 of the second adhesive layer 2 satisfy T1 < T2. The visible light transmittance T1 of the first adhesive layer 1 and the visible light transmittance TS of the first substrate S preferably satisfy T1 < TS.
