Abstract
In a touch panel, upper and lower electrode connecting portions are provided in the vicinity of a sealing agent formed above extending electrodes, and the upper and lower electrode connecting portions are connected so as to overlap each other. Accordingly, a gap between a height of the overlap of the upper and lower electrode connecting portions and a height of the sealing agent is relaxed. In this way, it is possible to reduce occurrence of cracks on the touch panel upon pressurizing upper and lower substrates.
Claims4
A touch panel comprising:
- an upper substrate including a transparent conductive film and an upper position detection electrode on a surface thereof, the upper position detection electrode having an upper electrode connecting portion;
- and
- a lower substrate including a transparent conductive film, a lower position detection electrode, and an extending electrode on a surface thereof, the extending electrode having a lower electrode connecting portion,
- the upper substrate and the lower substrate being bonded together, with a sealing agent interposed therebetween, wherein:
- the transparent conductive film of the upper substrate and the transparent conductive film of the lower substrate face each other,
- the lower electrode connecting portion has a concave shape and has a conductive adhesive applied thereto such that the lower connecting portion overlaps and is electrically connected to the upper electrode connecting portion,
- the upper and lower electrode connecting portions are in a vicinity of a portion of the extending electrode where the sealing agent is disposed, and
- a combined height of the upper and lower electrode connecting portions is more than a combined height of the extending electrode and overlapping sealing agent.
