Title:
TOUCH SCREEN
Document Type and Number:
WIPO Patent Application WO/2014/050306
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a touch screen having a small cross capacitance between row-direction wiring and column-direction wiring and in which there is a larger amount of change in the cross capacitance when touched by an indicating body. In the touch screen (1), the row-direction wiring (21) comprises a first portion (E1) and a second portion (E2) having a smaller wiring width (W2) than the wiring width (W1) of the first portion (E1). The wiring width (Wc) of the column-direction wiring (31) is smaller than the length (M2) of the second portion (E2) in the row direction. The row-direction wiring (21) and the column-direction wiring (31) intersect in the second portion (E2). In the intersecting portion, a gap is formed in plane view between the row-direction wiring (21) and the column-direction wiring (31). The touch screen (1) is further provided with floating wiring (21a), which fills the gap in plane view. The floating wiring (21a) is formed in the same layer as the row-direction wiring (21) and column-direction wiring (31) and is insulated from both wirings.
