Abstract
A touch panel uses a plurality of spacers shaped in the form of a letter L. The L-shape spacers can be manufactured by densely patterning the shapes of L in a certain specific orientation on a spacer sheet. Thus, a large number of such spacers can be made available out of a unit spacer sheet of a certain specific size, at a lowered rate of loss in the material utilization.
Claims2
A touch panel comprising:
- a light transmitting lower substrate having a lower conductive layer on an upper surface thereof,
- a light transmitting upper substrate with an upper conductive layer on a lower surface thereof, a space formed between said lower conductive layer and said upper conductive layer, and
- a plurality of sheet spacers disposed between said upper conductive layer and said lower conductive layer, said spacers being provided with adhesive layers on an upper surface and a lower surface thereof;
- wherein
- the plurality of spacers are provided along sides of the upper and the lower substrates, and
- said spacers are L shaped.
