摘要： A low loss, small scale piezoelectric transformer, suited for a cold cathode tube load, and having a high effective coupling factor, is provided using a piezoelectric plate having a single polarization direction. Controlling the dimensions of the third electrode portion 15a constituting the high impedance portion makes it possible easily to adjust the capacitance of the electrostatic capacitor formed between the first electrode portion 12 and the third electrode portion in accordance with the load. Also, the second electrode portion 13 and the fourth electrode portion 15b constituting the low impedance portion are substantially equal in area and the third electrode portion and the fourth electrode portion are formed in one piece, so that energy propagation efficiency can be increased. Consequently, the effective coupling factor resulting from the electrode structure and the vibration mode can be kept high even if the capacitance is changed freely, and thus high element efficiency and a small amount of generated heat can be maintained and stress can be decreased.

摘要： An ATM of the present invention includes a liquid crystal display panel having, between two transparent substrates, (i) an image forming layer including at least a liquid crystal layer and a pixel section in which RGB pixels are arranged in a matrix manner, and (ii) a plurality of barriers (16) for splitting a display image formed by the image forming layer into a plurality of images each having a specific viewing angle. The plurality of barriers are provided so as to face the image forming layer. The plurality of barriers (16) are extended in a horizontal direction (lateral direction) parallel to the surfaces of the transparent substrates, and provided at substantially regular intervals in a direction perpendicular to the horizontal direction, parallel to the surfaces of the transparent substrates (i.e., in a longitudinal direction). This makes it possible to provide an ATM that prevents a peep at private information such as a secret number without giving, whichever direction a display is viewed, a false recognition that the display is in a resting state.

摘要： A display section of a portable phone includes a first polarizer, a switching panel section, a reflective polarizer, and a main panel section. The switching panel section has a liquid crystal layer including a plurality of regions having at least two different alignment directions. This makes it possible, by utilizing the difference in the alignment direction of the liquid crystal layer, to make the image difficult to observe by a sight-line from an oblique direction. Furthermore, it is also possible, by utilizing the mirror-surface displaying caused by the reflective polarizer, to make the image significantly difficult to observe.
