For the purpose of changing, in an external connection terminal of a display device that transmits a plurality of polarities of the image signals, the positions of pairs of electrodes to which signals of different polarities are applied, a display device includes a display area having a plurality of pixels, a wiring area in which a plurality of wires corresponding to the plurality of pixels are arranged, and an external connection terminal having a plurality of electrodes to which image signals to be transmitted to the plurality of wires are applied. In the display device, polarities of the image signals transmitted to wires adjacent to each other among the plurality of wires are different from each other in the display area. In the display device, the order of arrangement of the plurality of electrodes is different from the order of the image signals transmitted to the plurality of wires of the display area.

Display device having external connection terminal

A display device includes a TFT layer provided in a display area, a bending section and a terminal in a non-active area, and a terminal wiring line that connects to the terminal through the bending section, and the terminal wiring line includes a first wiring line and a second wiring line each positioned on both sides of the bending section and a third wiring line that passes through the bending section and is electrically connected with each of the first wiring line and the second wiring line and curved so as to have recesses and protrusions.

Display device

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

Provided is a circuit board in which visibility of an alignment mark is improved. In a case of manufacturing a substrate module in which a touch panel () and an FPC () are electrically connected, an alignment mark in the FPC () is formed by an opaque metal film, so that visibility is high. Consequently, when an alignment mark () in the touch panel () is also formed by an opaque metal film, the visibility of the alignment mark () also becomes high. By performing alignment using the alignment marks having high visibility, alignment between the touch panel () and the FPC () can be performed easily with high precision. As a result, the yield of the substrate module increases and modification of an alignment apparatus used for alignment becomes unnecessary, so that the manufacturing cost of the substrate module can be decreased.

Circuit board, substrate module, and display device

Affixed to a projection () of a glass substrate () included in a liquid crystal module () are a first ACF (), which has low surface tack strength but high connection reliability, and a second ACF (), which has high component attaching capability attributed to high surface tack strength. With these, an LSI chip (), electronic components (), etc., are mounted on the glass substrate (), so that high-speed electronic component mounting can be achieved while ensuring connection reliability.

Board module and fabrication method thereof

The invention provides a display panel and display device enabling easy connection to an external connection component depending on the type of a mounted component, and provides a display device manufacturing method allowing a simple manufacturing process. The display panel of the present invention is a display panel in which a thin film transistor array substrate and an opposed substrate are disposed opposing each other. The thin film transistor array substrate has a first routing wiring that is routed at the outer edge of the substrate, a common transfer section that is formed at a position overlapping with the first routing wiring when the substrate surface is viewed from a normal direction, and a first terminal region, having a plurality of terminals formed thereon including a terminal that is joined to the first routing wiring, at an end portion of the substrate. The opposed substrate has a second routing wiring, and a second terminal region, having a plurality of terminals formed thereon including a terminal that is joined to the second routing wiring, at an end portion of the substrate. The first routing wiring and the second routing wiring conduct with each other via the common transfer section.

Display panel, display device, and method manufacturing same

A liquid crystal display device () includes a glass substrate () having an LSI chip () and an FPC board () mounted thereon. A component ACF () made of a single sheet is used to further mount discrete electronic components such as stabilizing capacitors () on the glass substrate (). The component ACF () has a size that covers not only a region where the discrete electronic components are to be mounted, but also the top surfaces of the LSI chip () and the FPC board () which are mounted first. By thus using the large component ACF (), a positional constraint upon adhering the component ACF () to the glass substrate () is eliminated, reducing the area of a region where the discrete electronic components are mounted. By this, a board module miniaturized by reducing the area of a region where discrete electronic components are mounted is provided.
