Touch panel
A touch panel including a light-transmissive upper substrate, a light-transmissive lower substrate, an upper wave plate, a polarizing plate, a lower wave plate, and a first cover layer. An upper conductive layer is formed at a lower face of the upper substrate, and a lower conductive layer is formed at a top face of the lower substrate. This lower conductive layer is formed facing the upper conductive layer with a predetermined space in between. The upper wave plate is formed at a top face of the upper substrate. The polarizing plate is formed at a top face of the upper wave plate. The lower wave plate is formed at a lower face of the lower substrate. The first cover layer is formed at a lower face of the lower wave plate. This structure offers a touch panel which is resistant to damage to the lower wave plate and provides good viewability.
1 . A touch panel, comprising:
a light-transmissive upper substrate having an upper conductive layer formed at a lower face thereof;
a light-transmissive lower substrate having a lower conductive layer formed at a top face thereof, the lower conductive layer facing to the upper conductive layer with a predetermined space in between;
an upper wave plate formed at a top face of the upper substrate;
a polarizing plate formed at a top face of the upper wave plate;
a lower wave plate formed at a lower face of the lower substrate; and
a first cover layer formed at a lower face of the lower wave plate.
2 . The touch panel of claim 1 , further comprising:
a second cover layer formed at a top face of the lower wave plate.
