Provided is connection wiring capable of inhibiting connection defects between bumps and pads at the time of semiconductor chip mounting and also allowing an increase in the number of pads. In an area between a pad row in any stage and a pad row in an adjacent stage, a first lineis disposed so as to pass under an adjacent second line, or a second lineis disposed so as to pass over an adjacent first line. In this case, three lines are disposed in any area between padsin each stage such that the three lines include a first linesituated in the middle, and second linesare situated so as to have the first linepositioned therebetween. Thus, the pitch between the padscan be further reduced without reducing the width of the pads

Connection wiring

In order to inhibit defective connection between a bump of a semiconductor chip and an electrode pad of a substrate, a semiconductor device includes a substrate provided on a surface with a plurality of electrode pads, a semiconductor chipprovided on a surface with a plurality of bumpssubstantially equal in size, and an anisotropic conductive filminterposed between the plurality of bumpsand the plurality of electrode padsand electrically connecting each of the bumpsand corresponding one of the electrode pads. The plurality of electrode padsincludes a plurality of first electrode padsA positioned closest to an endof the semiconductor chip, and a plurality of second electrode padsB positioned inside the plurality of first electrode padsA on the semiconductor chip. Each of the second electrode padsB is larger in area than each of the first electrode padsA.

Semiconductor device

A liquid crystal display device includes a liquid crystal panel, a panel driver board, and flexible circuit boards. The liquid crystal panel has a substantially round shape and includes linear edge sections formed by linearly cutting out outer edge portions. The panel driver board is configured to supply signals related to image display to the liquid crystal panel. The flexible circuit boards include first ends and second ends. The first ends are mounted to the liquid crystal panel aligned with the linear edge sections with respect to the circumferential direction in a non-display area. The second ends are mounted to the panel driver board. Portions of the flexible circuit boards joining the first ends and the second ends have bending shapes in a plan view.

Display device

A liquid crystal display device includes: a liquid crystal panel having a display area and non-display area; a flexible substrate in the non-display area and connected to a control circuit substrate; a plurality of drivers in the non-display area; a plurality of connection wiring lines in the non-display area for connecting the flexible substrate to the plurality of drivers; a first driver; a second driver that is arranged further away from the flexible substrate than the first driver; a non-overlapping connection wiring line that connects the second driver to the flexible substrate and that does not overlap the first driver; and an overlapping connection wiring line that connects the second driver to the flexible substrate and that has a least a portion thereof overlapping the first driver.

A display moduleof the present invention includes a first board, a second board, a base film, and a circuit member. The first boardand the second boardare bonded together to face with each other. The base filmis provided between the first boardand the second boardand extends outwardly from an end of the first board. The base filmhas an insulating property and the extended portion is bent to an outer surface side of one of the first boardand the second board. The circuit memberis formed on the base film

Display module and display device

A display panel is connected to a wiring-mounted board on which a signal supply wiring that supplies wiring supplies signals for driving the display panel is mounted. The wiring-mounted board has (i) first and second wires extending toward the display panel, and (ii) first and second terminals that are connected to the first and second wires, respectively. The display panel has a first short-circuit wire that is connected to the first and second wires at a connecting part of the display panel and the wiring-mounted board, so as to short-circuit the first and second wires.
