Liquid crystal display device with cut-out portions in lead electrodes for connection to driving circuit

Claim 1

A liquid crystal display device comprising: two sheets of polymer film substrates being kept apart from each other; two of transparent electrodes laminated respectively with inside surfaces of said respective polymer film substrates, said inside surfaces facing to each other; a seal material inserted between said two transparent electrodes so as to form a display area in a space defined by said seal material and said two transparent electrodes, said display area being sealed with liquid crystal; two of electrode lead-out portions extending respectively from edge portions of said respective polymer film substrates together with said transparent electrodes in one direction outwardly from said display area; an external circuit substrate inserted between said two extended transparent electrodes at said two electrode lead-out portions; and at least one cut-out portion formed on at least one of said two electrode lead-out portions so as to expose one portion of said external circuit substrate inserted between said two transparent electrodes, said exposed portion of said external circuit substrate being electrically connected to an external driving circuit.
