TOUCH PANEL AND DISPLAY DEVICE

摘要

Provided is an electrostatic capacitance type touch panel, wherein lead lines are connected to respective end portions of at least either one of the X electrodes and the Y electrodes respectively, the touch panel further comprises an inspection electrode which is laminated to respective end portions of the at least either one of the X electrodes and the Y electrodes with an insulation film sandwiched therebetween on a side where the lead lines are not connected to the at least either one of the X electrodes and the Y electrodes, and a voltage for inspection is supplied to the inspection electrode during an inspection time and a voltage at the same phase as the drive voltage supplied to the at least either one of the X electrodes and the Y electrodes is supplied to the inspection electrode during a usual operation time.

主权项

1. An electrostatic capacitance type touch panel comprising:
a substrate; a plurality of X electrodes which are formed over the substrate, the plurality of X electrodes extending in a second direction and being arranged in a first direction which intersects with the second direction; and a plurality of Y electrodes which are formed over the substrate, the plurality of Y electrodes extending in the first direction while intersecting with the X electrodes and being arranged in the second direction; a drive voltage being supplied to the plurality of Y electrodes from one side of the plurality of Y electrodes, wherein lead lines are connected to respective one-end portions of the Y electrodes, the Y electrodes is divided into first and second groups, and the lead lines which are connected to the respective one-end portions of the Y electrodes in the first group and the lead lines which are connected to the respective one-end portions of the Y electrodes in the second group are led out in directions different from each other, the Y electrodes in the first and second groups have inspection portions at respective other-end portions where the lead lines are not connected, for inspecting electrical connection of the Y electrodes respectively, the touch panel further comprises a continuous first inspection electrode which is laminated to and faces respective ones of the inspection portions in the first group with an insulation film sandwiched therebetween, and a continuous second inspection electrode which is laminated to and faces respective ones of the inspection portions in the second group with an insulation film sandwiched therebetween, and a voltage for inspection is supplied to the first inspection electrode and the second inspection electrode and detected through the lead lines during an inspection time and a voltage at the same phase as the drive voltage supplied to the Y electrodes is supplied to the first inspection electrode and the second inspection electrode during a usual operation time.
