Abstract: The present invention aims at miniaturizing a balance-unbalance converter using the conventional connection lines and reducing the cost thereof. The present invention provides a high frequency electronic circuit component constituted by three transmission lines formed on at least the same surface, wherein the first and second transmission lines face each other on the same surface and are connected to each other electromagnetically, and the first and third transmission lines face each other on the same surface and are connected to each other electromagnetically.

Abstract: A liquid crystal display element utilizing flexible gas barrier films decreases poor display performance caused by bubble formation. This decrease is achieved by reducing the permeation of gas and water vapor from the gas barrier films into substrates by devising the structure of the element and the configuration in which the element is mounted. Specifically, edges of the substrates forming the liquid crystal display elements are sealed. Additionally, the gas and water vapor saturation solubilities of the liquid crystal material is controlled to improve resistance to bubble formation. The liquid crystal display elements can also be subjected to and/or stored in a reduced pressure. Electronic equipment incorporating liquid crystal display elements can include a guard plate having a minimum thickness and/or spacing from the display elements.
