Abstract: 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.

Abstract: A thin film transistor array panel device comprises: a base substrate; a barrier layer disposed over the base substrate and comprising a plurality of transparent material layers; and an array of thin film transistors disposed over the barrier layer. A difference between a refractive index of the barrier layer and a refractive index of the base substrate may be within about 6%. The transparent material layers may be arranged such that the transparent material layers having compressive residual stress and the transparent material layers having tensile residual stress are alternately stacked. Each of the transparent material layers may comprise silicon oxynitride (SiON).
