Abstract
A liquid crystal display device having a liquid crystal panel LCP and a touch panel TP provided on the front surface of the liquid crystal panel is characterized in that wires connected to the liquid crystal panel and wires connected to the touch panel are included in one flexible printed circuit FPC, which is first connected (FOG1) to the liquid crystal panel (specifically, a TFT substrate (TFTS)) and then connected (FOG2) to the touch panel.
Claims10
An image display device comprising an image display panel and a touch panel provided on the front surface of the image display panel, wherein
- first wires connected to the image display panel and second wires connected to the touch panel are provided in one flexible printed circuit, and
- the flexible printed circuit has a first connection and a second connection connected in an order of the first connection and the first wires being firstly connected to terminals in the image display panel and then the second connection and the second wires being secondly connected to terminals in the touch panel;
- wherein both of the first and second wires and the first and second connections have different properties so as to enable connection of the flexible printed circuit with the image display panel and with the touch panel with high precision and without becoming defective.
An image display device comprising an image display panel and a touch panel provided on the front surface of the image display panel, wherein
- the touch panel has front terminal electrodes provided on the front surface of the touch panel substrate and rear terminal electrodes provided on the rear surface of the touch panel substrate,
- the touch panel comprises wires connected to the front terminal electrodes and wires connected to the rear terminal electrodes in one flexible printed circuit, and
- the front terminal electrodes and the rear terminal electrodes on the touch panel are respectively connected to the flexible printed circuit using anisotropic conductive films in such a manner that the glass transition temperature of the resin that forms the anisotropic conductive film is different between the anisotropic conductive film used for the front terminal electrodes and the anisotropic conductive film used for the rear terminal electrodes.
