摘要： A biometric information sensor includes a first substrate and a first sensor electrode disposed on the first substrate. A second sensor electrode is disposed on the first substrate at a same distance from the first substrate as the first sensor electrode. The second sensor electrode is spaced apart from the first sensor electrode. A piezoelectric layer is disposed between the first sensor electrode and the second sensor electrode. A second substrate is disposed on the first sensor electrode, the second sensor electrode, and the piezoelectric layer.

摘要： A touch sensor includes: a first insulating layer disposed on a substrate; a plurality of first touch sensing cells disposed on the first insulating layer and coupled to each other in a first direction by first coupling patterns; a plurality of second touch sensing cells disposed on the first insulating layer and coupled to each other in a second direction by second coupling patterns; and a second insulating layer disposed on the first touch sensing cells and the second touch sensing cells. At least one of the first insulating layer or the second insulating layer includes a piezoelectric material.
