COMPOSITION OF PIEZOELECTRIC MATERIAL, METHOD FOR FABRICATING THE SAME, PIEZOELECTRIC DEVICE, AND DISPLAY APPARATUS
To provide a composition of a piezoelectric material having high piezoelectric properties without lead.SOLUTION: A piezoelectric device comprises: a piezoelectric device layer including a first material layer and a second material layer surrounded by the first material layer; a first electrode part disposed on a first surface of the piezoelectric device layer; and a second electrode part disposed on a second surface facing the first surface, where the piezoelectric device layer satisfies the composition of 0.96(Na0.5K0.5)(Nb1-x,Sbx)-0.04SrZrO3+1 mol% CuO, where x satisfies 0
【課題】鉛を含まずに、高圧電特性を有する圧電材料組成物を提供する。【解決手段】本明細書の実施例に係る圧電素子は、第１物質層および第１物質層によって囲まれた第２物質層を含む圧電素子層、および圧電素子層の第１面に配置された第１電極部、および第１面に対向する第２面に配置された第２電極部を含み、圧電素子層は、0.96(Na0.5K0.5)(Nb1-x,Sbx)-0.04SrZrO3+1mol％ CuO（式中、ｘは、０＜ｘ＜０．０６である）の組成を満足する。【選択図】図２Ａ
