Abstract
A flexible printed circuit board has one end to be soldered to the terminal section of a display device, such as a liquid crystal display, the terminal section being used for connection to an external circuit. The end of the circuit board is provided with a pair of protrusions on opposite sides. The display device has a small base sheet and a large base sheet bonded together to form a cell. When the protrusions are caused to bear on the side of the cell, a given gap is formed between the portion of the aforementioned end other than the protrusions and the small base sheet of the display device.
