摘要： In a touch panel device for detecting a position touched by an object by sensing an attenuation or break of surface acoustic waves, in which IDTs for exciting or receiving surface acoustic waves comprising comb-like electrode fingers aligned along confronting bus electrodes are placed on a peripheral area of a substrate, drawing electrodes connected to the bus electrode positioned closer to the center of the substrate and led out to the peripheral area side of the substrate are provided. Each of the IDT regions segmented by the drawing electrodes is constituted by repetition, and the drawing electrodes are disposed so that impedance in each IDT region becomes equal.

摘要： A piezoelectric element includes a substrate, a lower electrode on the substrate, a piezoelectric layer on the lower electrode, and an upper electrode on the piezoelectric layer. The upper electrode includes a common base and a plurality of parallel branches extending from the base. The branches are arranged at a regular interval or pitch λ1. The lower electrode faces the branches of the upper electrode via the piezoelectric layer. The thickness h of the piezoelectric layer and the branch pitch λ1 are determined to satisfy an inequality 0.005≦h/λ1≦0.1. The lower electrode has a hillock occurrence rate which is no greater than 0.1%.

摘要： First electrodes partially configuring light-emitting elements are patterned in the form of stripes on a first major surface of a transparent substrate. Next, piezoelectric elements functioning a SAW touch sensor are formed on a second major surface of the transparent substrate. Next, the light-emitting elements forming step of forming light-emitting elements on the first electrodes which are patterned in advance is sequentially executed. After the formation of the piezoelectric elements, since the step of forming the light-emitting elements is executed, the light-emitting elements can be prevented from being damaged by receiving heat in the formation of the piezoelectric elements.
