Title:
MULTILAYER BODY HAVING FUNCTION OF TRANSPARENT CONDUCTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2023/106314
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a multilayer body which is capable of maintaining high transmittance, while preventing an increase in the resistivity due to annealing. The present disclosure provides a multilayer body which is obtained by stacking an IZO film and an oxide film, wherein: in cases where the multilayer body is subjected to annealing at 350°C in the atmosphere, the surface resistivity of the multilayer body is 200 Ω/sq. or less; and in cases where the multilayer body is subjected to annealing at 350°C in the atmosphere, the average transmittance of visible light (wavelength: 380-780 nm) is 85% or more. The present disclosure also provides a multilayer body which is obtained by stacking an IZO film and an oxide film, wherein: if Rs0 is the surface resistivity of the multilayer body in cases where the multilayer body is not subjected to annealing, and Rs1 is the surface resistivity of the multilayer body in cases where the multilayer body is subjected to annealing at 350°C in the atmosphere, Rs1/Rs0 ≤ 10.0 is satisfied; and in cases where the multilayer body is subjected to annealing at 350°C in the atmosphere, the average transmittance of visible light of the multilayer body is 85% or more.
