A terminalincludes a terminal connection portionconnected to a counterpart terminal and a board connection portionconnected to a conductive pathof a board. The board connection portionhas a plate shape portionthat is a plate shape. The plate shape portion is disposed behind the terminal connection portionand is soldered to the conductive pathof the board. The board connection portion has a plate-shape first projection wallsA toD that are bent from edge portions of a lateral direction side of the plate shape portionand that project to an opposite side to the boardside. The plate shape portionand the first projection wallsA toD have a plating layerthat is formed on a plate surface of the plate shape portion and the first projection walls.

A method of driving a matrix-type liquid crystal display device utilizing a liquid crystal layer sandwiched between a plurality of scanning electrodes and a plurality of signal electrodes extending generally perpendicular to the scanning electrodes, which comprises the steps of erasing a display screen by bringing it into either a light transmitting state or a light scattering state, writing by which pixels each at a point of intersection between the scanning and signal electrodes are selectively reversed in optical state, and retaining each of the pixels in the optical state once assumed immediately after the writing step. During the erasing step, all of the pixels are applied with a high alternating voltage or a high direct current voltage. During the writing step, the scanning electrodes are line-sequentially selected and the signal electrodes are applied with a signal of a waveform effective to apply a high voltage to some of the pixels desired to be reversed in optical state and a low voltage to some of the pixels desired to be retained. During the retaining step, a low alternating voltage or a low direct current voltage is applied to all of the pixels. One of the voltage wave applied to the pixels during the writing step and that applied thereto during the erasing step is high and low, respectively.
