Document Type and Number:
Japanese Patent JP6996143
Kind Code:
B2
Abstract:
To provide a piezoelectric sensor, a touch panel, a touch type input device, and a display that prevent a reduction in yield and prevent the occurrence of cracks.SOLUTION: A piezoelectric sensor comprises a piezoelectric film that is drawn in a uniaxial direction and includes a chiral polymer. When the length of a long side of the piezoelectric film is L1, the length of a short side is L2, and an angle in the drawing direction with respect to the short side is θ, the following relationship is satisfied. f(L1)≤θ≤90-f(L2), wherein f(x)=a x+b.SELECTED DRAWING: Figure 6
