Abstract:
PROBLEM TO BE SOLVED: To provide a double-sided adhesive sheet which makes a pattern of a conductive part invisible while maintaining enough adhesive force when applied to a conductive member having the conductive part in a part on a transparent support, and which gives good visibility of a screen when used for bonding the conductive member and a display device.SOLUTION: The double-sided adhesive sheet satisfies the condition of expression (1): (Δb)/Hz>0.40 and has a haze value of 5% or more. In expression (1), Δb=b-b, where brepresents a bvalue of the double-sided adhesive sheet measured with transmitted light, brepresents a bvalue of the double-sided adhesive sheet measured with reflected light; and Hz represents a haze value of the double-sided adhesive sheet.SELECTED DRAWING: Figure 1
