Patent ID: 8319109

Claim:
An electro-optical device comprising: an electro-optical panel having a pair of substrates, a liquid crystal layer disposed between the pair of substrates, a scan line driving circuit, a sampling circuit, and a panel-side external connection terminal for inputting/outputting signals from an external device to the electro-optical panel for electro-optical operations; a first wiring board having a first wiring forming surface, the first wiring forming surface being formed with wirings, a one-side first connection terminal electrically connected to the panel-side external connection terminal at one end of the first wiring forming surface and an other-side first connection terminal at the other end of the first wiring forming surface; a second wiring board having a second wiring forming surface, the second wiring forming surface being formed with wirings, a one-side second connection terminal electrically connected to the other-side first connection terminal at one end of the second wiring forming surface and an other-side second connection terminal at the other end of the second wiring forming surface for electrically connecting to an external connector of the external device; and a case for containing the electro-optical panel, the case being fixed to at least a part of a substrate surface of one of the pair of substrates, the substrate surface facing away from the other of the pair of substrates, the case having a plate-shaped reinforcement member, wherein: the plate-shaped reinforcement member is mounted on a back surface of the first wiring board, the back surface being located opposite the first wiring forming surface, such that the plate-shaped reinforcement member reinforces the first wiring board from the back surface, the plate-shaped reinforcement member extends from the electro-optical panel to a position directly facing the second wiring forming surface of the second wiring board, the portion of the plate-shaped reinforcement member directly facing the second wiring forming surface being directly adhered by an adhesive to the second wiring forming surface, and the second wiring board is a flexible board having an unreinforced region that is not adjacent to the plate-shaped reinforcement member, the unreinforced region extending between the portion of the second wiring forming surface that is adhered to the plate-shaped reinforcement member and the other-side second connection terminal.
