Abstract: A flexible wiring board includes a base member having flexibility, a write terminal section which is formed on the base member and which is a section to be protected, a protecting section which is integrally formed with the base member and which is folded back so as to cover the write terminal section, and a slit which is formed in the base member in a position that overlaps with the protecting section in a folded state and into which the protecting section can be inserted.

Abstract: Disclosed is a liquid crystal device having improved assembly workability. A liquid crystal device of the present invention is provided with: a liquid crystal panel 31; a liquid crystal panel driver 21 that drives the liquid crystal panel 31; a touch panel 50 disposed on the display surface side of the liquid crystal panel 31; a touch panel driver 22 that drives the touch panel 50; and a flexible substrate 40, which is electrically connected to a control circuit board 12 that controls a drive of the liquid crystal panel 31 and a drive of the touch panel 50. The liquid crystal panel driver 21 and the touch panel driver 22 are electrically connected to the control circuit substrate 12, respectively, through the same flexible substrate 40.

Abstract: The present invention has as its object to provide a flexible wiring board that is devised to retain the shape of the protecting section at a low cost. The flexible wiring board 13 includes a base member 22 having flexibility, a write terminal section 23 which is formed on the base member 22 and which is a section to be protected, a protecting section 25 which is integrally formed with the base member 22 and which is folded back so as to cover the write terminal section 23, and a slit which is formed in the base member 22 in a position that overlaps with the protecting section 25 in a folded state and into which the protecting section 25 can be inserted. When the folded protecting section 25 is inserted into the slit 26, a portion of the protecting section 25 comes into contact with the surface 22b of the base member 22 on the side opposite from the surface 22a on the side of the write terminal section 23, thus making it possible to regulate the protecting section 25 returning to the original shape.

Abstract: Disclosed is a flexible circuit board connection structure that has a simple configuration, is inexpensive, and has superior connection reliability. The connection structure is a structure connecting a first flexible circuit board 40 and a second flexible circuit board 50 and is characterized in that a first through-hole 45 and a second through-hole 46 are formed in the first flexible circuit board 40, the second flexible circuit board 50 is inserted through the first through-hole 45 from the first surface 48 side of the first flexible circuit board 40 to the second surface 49 side of the same, and the second flexible circuit board 50, which has been inserted through to the second surface 49 side of the first flexible circuit board 40, is soldered to the first flexible circuit board 40 from the first surface 48 side of the first flexible circuit board 40 via the second through-hole 46.
