Document Type and Number:

WIPO Patent Application WO/2014/054484

Kind Code:

A1

Abstract:

This laminate has a glass film (2), a glass film (3), a glass film (4), and a transparent adhesive layer (5). The glass films (2, 4) form both of the outermost layers, and transparent conducting layers (6) are formed on both surfaces of the glass film (3). The glass films (2, 3, 4) are each 200 μm or less in thickness. The glass film laminate (1) for a touch panel takes on a bowed condition in and of itself even without application of outside force, forming a concave bowed portion (21) and a convex bowed portion (41), and producing compressive stress in the concave bowed portion (21), while producing tensile stress in the convex bowed portion (41).
