Abstract: A flexible circuit board includes a plurality of first wires that have a first connection area and a first insulating layer that covers the first wires such that the first connection area is exposed. A printed circuit board includes a plurality of second wires that have a second connection area, a second insulating layer that covers the second wires such that the second connection area is exposed, and a plurality of island conductors adjacent to the second wires across a gap. The second connection area is covered with an anisotropic conductive layer. Each of the second wires in the second connection area at least partially faces a corresponding one of the wires in the first connection area across the anisotropic conductive layer. The plurality of island conductors include an island conductor that is in contact with the anisotropic conductive layer and partially exposed from the anisotropic conductive layer.

Abstract: A liquid crystal display device includes: a liquid crystal display panel having gate bus lines extending along a row direction and source bus lines extending along a column direction; and a gate bus line driving circuit and a source bus line driving circuit. The pixels are disposed in a pixel array region, which includes: a first region where arbitrary displaying takes place; and a second region where exclusively black displaying takes place, the second region adjoining the first region along the column direction. The gate bus lines include a first group of gate bus lines disposed in the first region and a second group of gate bus lines disposed in the second region. The second group of gate bus lines include a first gate bus line connected to the gate bus line driving circuit and second gate bus lines connected to the first gate bus line via an interconnect.

Abstract: This thermocompression bonding device is provided with a heating tool (1) and a backup member (3). The backup member (3) has: a support portion (3a) which faces the tip (1a) of the heating tool (1) while first and second members (111, 122) to be joined and a cushioning member (2) are located therebetween, and which supports the first and second members (111, 122) to be joined; and a body portion (3b) provided on the opposite side of the support portion (3a) from the first and second members (111, 122) to be joined. The support portion (3a) is formed so that the heat conductivity thereof is lower than that of the body portion (3b).

Abstract: In one embodiment of the present invention, a liquid crystal display of the present invention contains an LCD (1) and an LCD (2). Adjacent pairs of polarizers form crossed Nicols. When the LCD (1) produces a display from a first display signal, the LCD (2) produces a display from a second display signal obtained from the first display signal. The gate driver for the LCD (1) and the gate driver for the LCD (2) producing a display from the second display signal are disposed symmetric. Accordingly, flickering is reduced which otherwise would be clearly visible when the two liquid crystal panels are stacked. A liquid crystal display with high display quality is thus realized.

Abstract: The display device includes a display panel and a plurality of wiring boards placed along the periphery of the display panel. The display panel has panel-side connection wiring for electrically connecting first and second wiring boards adjacent to each other among the plurality of wiring boards. Each of the plurality of wiring boards has an insulating base, a board-side wiring group running on the insulating base, and at least one driving circuit element for driving the display panel. The board-side wiring group is composed of element-connected wiring electrically connected to the driving circuit element and non-connected wiring having no electrical connection to the driving circuit element. The panel-side connection wiring is formed so that the element-connected wiring of the first wiring board and the non-connected wiring of the second wiring board are electrically connected to each other.
