ABSTRACT:
A fluorescent display device capable of realizing mounting of a semiconductor element on a substrate while ensuring an increase in moisture resistance, a decrease in contact resistance at connection between the semiconductor element and a wiring conductor and increased reliability. A semiconductor element is mounted on an extension of a substrate and received in a mounting chamber formed by cooperation of a sealing material, a face plate and the substrate. The semiconductor element is downwardly pressed against the substrate by the face plate, resulting in the semiconductor element being electrically connected to a wiring conductor. The sealing material is made of an inorganic material such as indium-tin alloy or the like which has an operating temperature lower than a sealing medium.
