Abstract
Abstract An LCD panel (45) has a plurality of terminal electrodes (45d) formed at a peripheral portion thereof. The LCD panel (45) is brought into contact with conductive contact elements (13) and fixed by fixing means (71) to be electrically connected to a circuit board (81). An insulator (11) has a first surface (11a) for mounting the peripheral portion of the LCD panel (45), and a second surface (11b) to be faced to the circuit board (11b). The contact elements (13) are fixedly mounted in the insulator (11) to be brought into contact with the terminal electrodes (45d), respectively, when the LCD panel (45) is disposed on the first surface (11a) of the insulator (11). The fixing means (71) clamps and fixedly holds the insulator (11) and the LCD panel (45) when the LCD panel (45) is disposed on the first surface (11a). The insulator (11) is combined with a header (100) to be mounted on the circuit board (81).
