摘要： A bulk acoustic wave filter device includes a substrate, a lower electrode on the substrate, a piezoelectric layer covering at least a portion of the lower electrode, and an upper electrode covering at least a portion of the piezoelectric layer. The upper electrode has a density reduction layer disposed on at least a portion thereof, except a central portion of a resonance region of the bulk acoustic wave filter device that deforms and vibrates with the piezoelectric layer during activation of the piezoelectric layer. The density reduction layer has a density lower than a density of other portions of the upper electrode.

摘要： Disclosed herein is a touch sensor including a window substrate, a bezel layer formed on an edge part of the window substrate, a reflective layer formed on the bezel layer, and electrode patterns formed in the bezel layer of the window substrate, wherein the bezel layer is formed of a transparent material. Thus, due to the formation of the bezel layer and the reflective layer of the touch sensor, bezel colors are effectively realized using a more thinned film bezel.
