Abstract
Abstract The display apparatus comprises a liquid crystal display element, a circuit board and electroconductive members interconnecting them. External terminals are formed on one substrate of the display element and input terminals are formed on the circuit board. The external terminals are electrically and mechanically interconnected by rigid electroconductive members through conductive films.
